Well the solution is quite easy if you now what you need to do

First of all the Require/Include schould be in your in index.php or something like that but not in your class, if you put them in your class the $vbulletin variable get out of scop, don't know why but it seems a matter of fact.

Now you just need to put a global $vbulletin into your function and the vbulletin functions are working.

Thanks a lot Christian vom vbulletin-germany.org for the help!

Cheers
