Well
excuse me (sarcasim) for having to move my dang websites to a Virtual Private Server! I do not go to vBulletin.org every day and I do not provide support everyday for products and scripts I make
24/7.
I've uploaded the script to my website and I do not seem to be able to reproduce the error you are receiving. Have you tried reuploading all the files (and overwrite)?
For anyone trying to use this with 3.7 Beta 4, it does work without any flaws.
