You need to allow command line access to bitcoind because the program needs to automatically check whether the password works.  See here:

https://en.bitcoin.it/wiki/Running_Bitcoin#Bitcoin.conf_Configuration_File

Basically you need to create a textfile named bitcoin.conf in C:\Users\username\AppData\Roaming\Bitcoin\ (change username to your username)

In the textfile you probably only need:

rpcuser=somename
rpcpassword=somepassword

Make the password a long gibberish thing

Once you have that file, open a command window (start, type cmd in the box, and select cmd.exe)
then type:
cd C:\Users\username\AppData\Roaming\Bitcoin\  (replacing username)
bitcoind --daemon

Count to 10 and type
bitcoind getinfo

If it gives you some information (current block, etc) that means you're connected and you can then run the ruby script
If it says not connected then count to 10 and try again.

That's fine, either: 
use 0.0001 in the box and send all but 0.0003
or use 0.0002 in the box and send all but 0.0006

The first box tells you that it would like to send the fee that you typed in the box (0.0001).  The second box means that it realized your transaction is so large it needs a bigger fee and it would like to use 3 times what you typed in the box.

Don't trust that recoinvery website.

First, what OS are you using?

There you go, check post #26.  You just need to install ruby.  You can delete the parts you don't need, since you just want to insert a character.

They're not warning you about the dangers of daytrading.  They're warning of the possibility that your exchange could steal or lose all your coins like Mt. Gox.

Goto Settings -> Options and change the fee to 0.0001 then retry the transaction and accept the fee.  Make it 0.0002 if you really want to be sure it'll go through.

What does this return:
bitcoind getinfo

Why do people move 2 BTC when they're not sure how it works -- why not 0.01 first as a test?

Do you have libboost_thread installed?

It's a pretty simple program.  If you can install python I can probably whip something up tonight, or somebody else might beat me.

There's no need to connect to the internet to make another offline wallet.  You shouldn't be connecting to the internet at all, even to make your first offline wallet.

Bitcoin-QT lets you encrypt your wallet, so you're all set already.

What's the accepted number?

I can't imagine why they would warn against overclocking, it seems perfectly safe.  It's not like it's going to just die after awhile.

Honestly your best bet is to take $400 and buy the remaining BTC.

But if you're set on doing it pure-BTC style, maybe someone wants to pay you to design some graphics for a webpage?  I think the shitcoins sometimes pay for people to make a coin logo for them.

When using a pool the difficulty is the quality of share you need to submit to get partial credit for a block that is found.  If 10,000 people each submit 1 1 difficulty share then they will each get 1/10000 of the block reward.

When solo mining you need to actually solve the block and so the difficulty is the actual solving difficulty.  You will get 100% of the block reward if you are successful.

It's only worth it if you want to do it "for fun".  You'll never make $40 worth of bitcoins with those.  And you can't use them for altcoins.  Don't listen to anyone who tells you to mine PPC with them.

Is it possible your power supply isn't powerful enough for both at the same time?

Try bitcoin-qt -rescan
What is the error blockchain.info gives you?
What are the addresses you have bitcoins at?  Does getaddressbyaccount show those addresses? (I've never used this command, so not sure if it will tell you anything useful)
  Or can you use pywallet to list all the addresses that your wallet.dat contains private keys for?

What does it say in the log file?
