Forum Blog and Project Tools not usable after upgrading to Vbulletin 4.0?
 

I kept receiving warnings and errors like the products are not compatible with vbulletin 4.0. What the heck is that? I purchased the three products for a total of $300 last year and now I can only use a forum? Is there anything I can do other than paying $250 for a Vbulletin 4.0 Suite?
