I tried uploading the cvs file but it keeps giving me an error "There was a problem uploading the CSV file. Try again, or choose another file." (i already downloaded and try to use the file given under the help forum)

Sorry you're stuck but there's almost always a pretty easy fix! Do NOT try to start all over again, uninstall Max's Pitch Package, etc. That can make it worse. There's a 95% chance the same snag/fix is listed & answered in the Help FAQ. But if you can't find it there, post your problem here.
Make sure you post in the right category below & be sure to include a screencap showing the issue!
The file must have gotten messed up when you downloaded it or afterwards. Did it open in Excel when you downloaded it? Have you viewed its contents to see if it looks ok?
Try emailing me at tim.hill@themaxlabsproject.com and attach the file to your message and I'll take a look.
