Conrad Hilton pled not guilty Thursday to violating a restraining order by showing up at his ex-girlfriend's doorstep ... but the bigger news is that he seems to be doing a lot better after getting some serious professional help.

A judge released Conrad on the condition he undergo treatment at a facility in Houston. Looks like it's mission accomplished.
