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!
Looks like maybe you tried a few times (?) which is not uncommon since you don't see anything in your browser window when you execute the command. It's ok just delete 3 of them if you want and leave one.
