I know this is in readme. I read it, uninstalled all prior plugins PLUS the invite plug... Plus a bunch of other plugins like cb search, and I still get the Error: No language file could be loaded problem...

This sucks.

I Found a fix for this problem.
BACKUP! then delete "invite.bot.php using FTP, file is in your /sitesname/mambots/system/

wish i woulda found this out BEFORE I trashed all my plugins... shit.
