I've upgraded to UniAdmin 0.78m and I'm getting the following error when I try to upload Atlas 1.9RC2:

[PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature]

I've tried rezipping the files into a full path version. I've set my max upload size to be 10M (the zip file is ~9mb). I've tried re-downloading the file multiple times. I've installed it on my computer, so I know it's working. I'm not sure what else to try, and advice?
