I got a set of roms and I tried to run CLRmame on them recently. I keep getting the following error on MANY files:

Tetris (Cocktail set 2) [folder: atetckt2 - parent: atetris]
Set skipped due to zipfile- or sharing-error. See warningswindow for details.

Corrupt Zipfile - Reason Bad or corrupt end of zip structure.

I thought that maybe I had an error copying the file from the dvd so I attempted to extract the zip file. I can extract the file without any problems so I don't know whats wrong.

Any help would be greatly appreciated.
