Windows 2KPro registration issue

[Paul Downey]

I am running Windows 2K Pro. I am using a Plextor Premium 52x. It was suggested to me by tech support at MTU that I needed the upgrade to support my burner. I have upgraded from Microstudio Ver 2.4 to 2.517. Using the registration email and code that I was supplied with, I have tried unsuccessfully to register the new programme. The error message I get back differs from attempt to attempt e.g. your email is incorrect/registration code is incorrect. Its very vague. I have tried asking different friends (computer technicians) to try this for me and still no luck. I have read the forums and dont seem to be any closer to success. I still cant use this programme. The original ver 2.4 doesnt support my burner and I am without any useable product. Feel very let down by the amount of time and effort and money spent to register.
