Yes I did. I have since uninstalled it and all is working again. Why was it corrupted and should I re-download the program? While it was installed, PTLE wouldn't boot at all but was showing in task manager using 99% of my CPU. I understand this is an issue with Pentium M's. I just bought the laptop and was setting everything up. The new version has been working flawlessly on my Mac. Cary HP Pavillion DV 1000 1G Ram 80GB HD 1.7GHz Pentium M Digi 002 and MBox PTLE 7.0cs6
