nonce must be greater than / modal dialog

[ytoto]

Hello,

This is my first try of QtBitcoinTrader and have this error poping up every 0.5 to 10 seconds, so making it practically unusable. I'm testing the win64 version 1.4.0.43 downloaded from sf.net.

The message shows:
nonce must be greater than 'some number > 2^32'. You provided 'some number < 2^31'

This error means that you tried to use the same API keys with other apps.
It is important, one API key pair will work only with one app, and once you run another app, it breaks previous one.
