Computer Techs?? Stupid Playtopus Problem!!!

Hey everyone, I've been having this stupid Playtopus problem for several months now after I downloaded the Service Pack 2 for Vista. I "uninstalled" it but it remains and it still shows up in the programs. But, everytime I go to uninstall it, it says it can't find the program source.

I'm still getting the popups like crazy and I've tried researching on how to find the files in my computer but haven't had any luck in finding them.

Anyone have this problem before and was able to get rid of it without having to pay for some dumb "uninstall program" or something??

Help is MUCH appreciated!!!
