Ah, ha.. Thank you.
I figured it out, i had actually typed in my username and password in those fields rather than my worker name and password.. is this dangerous? I changed my main password anyway.
How would i find my private address for sending bitcoins or would i even need one? If it's encrypted on disk i assume that keeping backups are a good idea?
If i were to get another GPU, would i have to make a second installation folder for my bit-coin miner and then run the second program from there or do the mining programs support multi GPU systems?
Thanks again for the help.
