I have tried to upload the file so many times and it acts like it worked until I get to step 29 and I can only see 3 meetings. I checked the email it sent and it said 'Meetings Failed: 10 (we couldn't import these due to errors)'
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!
