Can't get missing sync to connect or bluetooth with computer

[white97supra]

I've been having trouble getting my missing sync or my computer to recognize my phone. Sometimes when I plug it in the missing sync loading screen pops up but then doesn't connect.

I'm not sure if this has to do with the fact that I did the WM6.1 update or not but I can't remember if it worked or not after I switched.

Also: Ever since I switched to 6.1 My microSD card isn't recognized by the phone creating annoying storage problems. Hoping you guys can help. thanks a lot.
