Uninstalling Rock Amp Legends Demo, Please help Options

[jgs22]

Hi, I downloaded a demo version of Rock Amp a fortnight ago and it has since expired. It wasn't what I was after so I was not planning to authorise it after expiry. Being knaive , I deleted the Rock Amp folder and bit and pieces after it had expired. My dilema is that now when i try to open Logic Audio 5.5 or Garage band, I get the message that the program has expired and I have to go to the PACE website to download extensions. It then quits from logic or Garage band. How do i uninstall Rock Amp and all its hidden files totally ?
