194202 Amember-vbulletin bridge issue

Yesterday I installed aMember with the vBulletin plug-in. I am having trouble getting current members with our vbulletin system into the amemeber system. I have done all the installations but there are several database errors and users need to log-in twice to see the forum - once with amember and then again with vbulletin. I need this done quickly. Thanks, Mike
