upgraded to 6.1 on xv6800, now can't active sync

Hope someone can help, posted this in howardsforums and got no response, think i need more expertise...

Upgraded my xv6800 to wm 6.1 2 weeks ago. All went well. However, now when I connect my phone to the computer, active sync does't pop up. And when I start AS, it shows not connected. I run connection wizard, can't find phone! Am running AS 4.5.

I tried this on 2 separate computers with 2 separate cables. Nothing works. Worked fine prior to doing the upgrade. When I try from the phone, get the AS symbol, but nothing happens.

Any help here is greatly appreciated! Thanks!
