@ILT: from the fact that you can't move at all I conclude that you have addons installed which are hooked to the movement keys. As this is not allowed anymore, a quick suggestion would be to look for any addon doing things "automagically" while running around, and disable them, the modified Decursive in auto-mode and Druid Bar being only two examples of probably quite a long list of addons. Perhaps a visit at
http://www.wowwiki.com/Broken_Addons..._and_Reporting would be helpful, where you find addons listed that were reported from the public test realms as "blocked".

P.S.: All this probably has got nothing to do with BibMod at all.
