bluetooth connects and disconnects

I have an iMac at work and a MacBook Pro at home. Both on Mountain Lion. I had my Razr Maxx paired to the iMac and I could connect with no problem. I tried setting it up on my MB and it would connect for a few seconds and then disconnect. So at work I unpaired the iMac and tried setting it up again. Now it's doing the same thing with my iMac and I can't keep it connected. I've tried various settings when the Allow Internet Sharing box pops up on my phone and various settings in the Bluetooth Mobile Phone Setup on the iMac (pic attached), but I can't get it back to how it was before I unpaired it. Does anyone know the proper setting I should use to this to work again?

Thanks

Forgot the pic

Any ideas?

Hoping one more bump will result in an answer to my issue
