Why do I get a data base error on my main Forum page after un-installing this xml?

Database error in vBulletin 4.1.3:

Invalid SQL:
SELECT id, name FROM vb4_dl2_categories;

MySQL Error : Table 'xxxx_vb4.vb4_dl2_categories' doesn't exist
Error Number : 1146

I want to take this mod out but I can't.
Anyone else had this problem and how did you un-install this product?
