That's what I meant. I deleted the program, and closed everything, and it still did not work. However, I go to my username on the computer folder, and I don't see any app data/ roaming folder, nor can I access it through command prompt, so what should I do then.
Errm, now I'm lost! If you didn't go to AppData/Roaming/poclbm - what did you delete?
If you open a command prompt it puts you in C:/Users/YourUsername, so you should be able to do directly:
cd appdata
cd roaming
cd poclbm
and then a 'dir' should list the files, including poclbm.
and a 'del poclbm' command should get rid of it. (Caveat - it is 'del' in windows isn't it, not 'rm'?)
Addendum: Or as auseeker has jsut posted, show those hidden folders!!!!
