Mmmmm.... the .bat file is unnecessary.
I would just go in and delete the addon preferences yourself. Make sure you exit WoW before you do this though.
Check the following folders for anything that is related to VuhDo with a .lua or .bak extension.
Code:
World of Warcraft\WTF\Account\youraccountname\SavedVariables
World of Warcraft\WTF\Account\youraccountname\servername\charactername\SavedVariables
If you find anything then delete those .lua or .bak files and restart WoW. If you don't find those files, then it isn't your preferences.
Oh, and don't delete ALL of your .lua and .bak files unless you want to spend some time re-setting up your addons. Just the VuhDo related files.
