Hmmm.. Reinstalling PBP is just copying files to a folder I thought. I think I need to do this, but am not sure exactly how to 'deinstall'. PBP does not show up in WinXP as a program that has a de-installer. I can move them out of a folder, restart, then put them back, but I don't see what that would do.

Also, I think the 16F88.bas file is corrupt because the installer tries to update it, but says it fails because of an unknown version of that 16f88.bas.... This is probably the reason for the odd behaviour.

I'll ping MELABS..

Thanks for all your help!
