CMS AdminCP widget admin unknown class
 

I just installed the vb4 suite. everything is great except i cant add or manage the widgets. on the widget manager page in admincp i get this error:

Quote:
Fatal error: Class 'vBCms_Item_Widget_CategoryNavBU' not found in /home/username/public_html/forums/packages/vbcms/collection/widget.php on line 234

im guessing im missing a class file somewhere. anyone know which one and where it goes?
