Forum in crash post installazione mod per avere i tab nel forum

Come da oggetto ho installato la mod [YUI] Tabbed Forum Home - vBulletin.org Forum
in seguito mi è andato in crash il forum e se tento di accedere ad esso ho i seguenti errori :

Database error in vBulletin 4.0.1:

Invalid SQL:
SELECT * FROM `tabs` WHERE `status`='1' ORDER BY `displayorder`;

MySQL Error : Table '****_***.tabs' doesn't exist
Error Number : 1146

se provo a gestire i tabs dal menu opzioni:

Database error in vBulletin 4.0.1:

allo stesso modo i moduli :

mi pare dicapire che c'è una tabella che manca ma come crearla "eventualmente" ? acceddo al db e la creo con quel nome?
ho provato anche a disinstallare il mod ma non me la fa rimuovere
