Help, how do I Fix Vista's RDC after uninstalling Comodo 3?

I succesfully uninstalled Comodo from the vista control panel (I think), but I STILL cannot RDC Remote Desktop Connect to this computer. I’ve tried everything, wasted about 6 hours of my time and i’m ■■■■■■ at comodo now, nothing but problems.

It gives me this error:

Remote Desktop Disconnected:
The Authentication certificate received from the remote computer has expired or is not valid.

I am clueless now, it was working no problem before Comodo. Any Ideas?

remote desktop fails for authentication certificate points out a possible explanation
