I didn't unzip the "upload" part of the logo editer..

Heh. The very first thing in my list of possible problems after seeing "error 53".

I'll get this damn computer stuff figured out one of these days

Best tip for computer novices: When one is experiencing problems and asking the experts for help, reporting the exact steps you took to make the problem happen, along with an exact description of the problem itself (especially the exact text of any error messages) is very important. Once you said "error 53", I knew where to start looking.
