Unable to load CorelDraw.dll Error Code:998

Having problems with Corel Draw running. I recieve the following error when I try to run Corel Draw X5 :- Unable to load CorelDraw.dll Error Code:998.

I have tried 3 re-installs of Corel Draw X5 but no luck.

There appears to be very little information online with this Corel Draw X5 error code.

Any ideas ?.

TIA
