Hello Dr. Blip,
My PCD was a bundled copy (provided by the manufacturer) when i purchased my HP pavilion desktop August, 2005. It had been running well till today. I printed a screen of the error message to a jpeg file and attached it below for your reference. I'm not sure if you can read Chinese. I tried to translate the error message literally as followed:
error message on my screen: “此机器未获得授权使用此版本的PC-Doctor。"
translation:"the system is not authorized to run current version of PCD"
Looking forward to your help.
Thanks in advance,
Regards,
Kan
