Cisco Firepower URL filtering not working

I have a pair of ASA5525's in Active/Standby.  For the past year, I've been running IPS on it, and I have a Virtual Defense Center setup in VMWare.  Last week I got a URL license for both  ASA's.   I installed the license, I assigned the license to my devices, I configured URL filtering, I applied my access control policy, and installed the user agent for AD.  All my AD users show up in the defense center and all looks like it should be working, but its not.  If I block a website or category for a specific user it doesn't block it, it just allows the user to go right through.  I opened a case up with TAC 3 days ago, after trouble shooting for a couple hours, he told me to upgrade to the latest version of 6.0, but I'm still having the problem.  My TAC engineer isn't in today, so we are going to resume working on it tomorrow.  In the mean time, I was wondering if anyone using Firepower URL filtering experienced anything similar and if so how they fixed it?  This doesn't seem like a hard task at all, but it doesn't seem to be working.  Let me know.  Thanks.
