After a long time of inactivity using an old version of electrum, a year ago, I downloaded the new one from electrum.org and I tried run it using all available ways (portable, standalone, windows executable). Trying to run it I faced these problems https://ibb.co/VvRZf33 and hitting OK https://ibb.co/r267NVk. All times before I hadn't any problem with electrum using same OS, that is, Win7 Sp1. I would appreciate any help.

I started recently to use electrum as a more secure wallet from my web wallet (I use blockchain.info). I use the portable version even though there is a warning in the sub-forum but I believe there is no difference with installed one. I have a couple of questions where I didn't find an answer neither in documentations page nor searching the forum or the net.

1. Tools--> Preferences --> Transactions (Use Multiple Change Addresses check box) what means? I already have checked the above that is Use Change Addresses and looking in tab Addresses I can see Receiving and clicking left arrow besides Change there are six addresses. So what is the difference between them?

2. Tools--> Preferences --> Transactions --> Coin Selection: (Privacy and Priority). What is the difference using first or second one.

If someone has the same confusion with me and has found the solution maybe wants to drop a line or post a link.

       Searching the web I found a video where the narrator had created a visual demo of blockchain technology in order to explain the procedures behind the bitcoins transactions. May be, this has a little to offer to experienced users since they know the whole process; but for newbies like me is very informative and self explanatory.
 
       So I thought that would be a good idea to share it with you https://www.youtube.com/watch?v=_160oMzblY8.

       If this not the right place mods are kindly requested to move it everywhere that should be.  

I made more than 22,000 Satoshis after Mon 11/7/2016 as FAQ of this site says http://www.paidbooks.com/faq but doesn't pay.

Does anyone knows anything about this faucet?
