This means that BOINC detected that one of the files that were downloaded from the E@H server was corrupted on your PC or during the download. You should check/repair your filesystem with scandisk first before letting E@H continue. Resetting the project might help to clear/reload any other E@H related files. If this happens frequently, this is an indication of a hardware defect.

Hope this helps

I was getting this error whenever I resumed a download that I previously suspended. I'm on dialup, so I'd like to be able to download partial files, and resume downloading later.
