The only advice I can give you is to read the Help section of MEW, especially the one titled offline. You are probably overlooking something.
If the problem continues to exist, erase the old MEW you are running and download it again from GitHub. Be careful not to erase the keystore file, if you have saved them in the same directory with the wallet.
Run everything again and I wish you, good luck, I hope this time everything works normally.

It would be better not to download files from unknown people, even from this Forum. If the file you'll get has a trojan or a keylogger then you may lose your money.
It would be better to send an email to the developers of the coin, about your problem. If they don't reply your emails I would stay away from this coin. Coins without developers are not a coin but a danger for your money.
Be careful.

Bitcoin is the first crypto ever created and the most known. I believe that his value is due to his fame than the abilities he has.
Ethereum is a "bitcoin" with a programming language in it.
This last thing gives him many possibilities to be expanded in the future and in my opinion, it can easily surpass bitcoins value.
It is ASIC resistant, that means you can mine it only with GPU.
The only negative is that has an unlimited supply.

I like both coins.
I think bitcoin is facing some problems this year with high fees and because it has moved too fast to 19k it needs some time to recover from the current 10k. Ethereum is doing great. The token that supports, help a lot and it has much lower fees than bitcoin, this is very positive.
I invest equally both coins but I always support Litecoin too, which I think is undervalued these days and will move fast this year.

It's worth trying, but be prepared for some loses too.
Trading isn't easy, books can help but you are going to learn by try and error. You'll read many success stories in this Forum, people are gaining money in trading alts and in ICO's. How many of the losers are telling their stories to us? Few of them.
Besides, I don't believe that day traders have time to visit and write to this Forum.
Remember, every time someone wins, there is a loser.

The bitcoin influences the other cryptocurrencies price, that's for sure. As it was said before, in the majority of the exchanges, trading is made in alts/btc. The inter currencies connection ends there.
What is happening in the crypto market is not the end of the world. There is no crash, just a price correction.
I think people are rushing to see bitcoin reaching 1 million and that can't happen within a year.
Altcoins will survive, and if not, other will come much better than the old ones.

I hope you'll find a solution soon.

The decentralized cryptocurrencies need to be mined in order to get them. This how they are made.
Without mining, the transactions cannot be confirmed, and we have nothing.
We can't change that, at least to the current existing crypto coins.
In order to stop it, another new coin has to be issued having that will be produced in another way.
Or if we want eco-friendly coins, we can accept centralized coins and give the profits to their creators.

I am using Bitcoin Checker it is a very easy app.
You can set up your favorite exchange and the coins you trade and keeps you informed at preset intervals about the current price of them.
If you want you to enable the alarms you can be informed when a coin reaches a specific price or you are gaining a specific percentage in order to sell or to buy. The only disadvantage it has is that you can't trade using it.

If I were you, I would add a third option "Both". If you are a good trader you can keep a percentage of your profit long-term just in case...
If you are a bad trader you could trade fewer alts than the coins you hold.
In any case, having a plan and sticking with it makes it easier when decisions are to be made.
I am a bad trader so I'm trading only the 10% of my total investment.

I don't think that Bitcoin is going to crash because it has a solid developer's team and many fans since the start of this crypto world. Even if it crashes, this new era of cryptos and blockchain is to stay. Many of the alts will survive and new promising coins are going to come to continue what bitcoin and the others started. So I think you have not to worry much about it, just choose the alts you invest with care, and try to avoid the scams.

If you have a Raspberry Pi ($35-45) you can use it as an offline computer keeping it off the net and changing the SD card.
It runs Linux, you can load any wallet (of any coin) you want and print paper wallets in a printer or sign your transactions.
When you are finished, change the card and save it in a secure place.
The card is minimal (mini SD) and you can hide it anywhere. This is my favorite cold storage method.

The prices of the cryptomarket coins are never stable, and it will never be.
You probably mean if we are going to see higher prices in the market.
Yes, we will, when we have better news from S.Korea and when the people do not have fear to invest. Cryptos will replace fiat in the coming future and the present financial system fights back. The majority of the investors want quick profits and don't care if the cryptos have future or not. That's why we have to hold, to protect our interest.

Don't put your eggs in the same basket. Ethereum is a great coin with potential, and we are going to see higher prices in the future.
It worths having it in your portfolio but it would be better to buy some other coins too. You have heard what happened some years when it was hacked and it lost his half value within a day. Find two more coins with a good reputation and divide your investment equally.
There are many good coins.

Normally, you keep your coins to the exchange only if you trade regularly. If you buy and sell these coins many times a day or week, it would be better to keep them in the exchange. You will pay fewer fees for your transactions.
If you want to hold your coins for long periods I'd suggest you send them to your cold storage wallet for more safety.
We all know what happened to MtGox a few years ago.

As long as you can't buy your living and pay your bills with it, it is not advisable to keep all your money in Bitcoins. If one day in the future that will be possible, it means that the price will be more stable and it will be accepted by authorities and of course by the people.
Until the day that the volatility of the price is a past, fiat should be your main saving and cryptos a small percentage of it.

If you bought $70 of bitcoin at the 0.3 price on January 1, 2011, you’d bought 233.33 bitcoins worthing today 2.5 million dollars. It seems that even today there are people among us who don't believe in Cryptos and think that what is done in Bitcoin is done and can't be replied. I am not among them but being not an expert I am not in the position to tell you what is this next coin. Do your research trying to avoid scam coins and other's futile opinions and when you find this magic coin, just hold it.

It seems you are not made for the trading. It doesn't matter I am not made for trading too. You may be good as a holder.
If you lost the half of your money, I would advise you to invest the rest in some good crypto coins and forget everything for some months. Don't check the prices daily. The crypto market is in short-term volatile but in long-term it gives back big profits.
Don't forget to make some investigation before investing your money.

You can use Ethplorer :
https://ethplorer.io/
in order to view your tokens, if you still want to view the tokens in MEW you can do it but you have to enter your tokens one by one manually.
Press the token name in Ethplorer / Token Balances and copy the Token CharterCoin Information.
In MEW press Add custom Wallet and enter the Token Contract Address, the Token symbol and the decimals and press save.
If all is ok you'll see your token listed in MEW too.

Bitcoin is designed from the beginning to have a high price. It follows the mining of gold. In the beginning, there is plenty of it and as time passes by it becomes more scarce and precious. 9 years after the first Bitcoin was mined, 80% of it is already mined and the rest 20% will be mining until 2140. Another explanation is that Bitcoin attracts people and investors, because of that high price and the promising profits it would bring.
