Strange bug

Hi Everybody,
I have (or had) the X6 suite installed on a 64 bit HP Computer.
Suddenly, DRAW started giving me this message.
.. "This application has requested the RUNTIME to terminate it in an
unusual way."
It then terminated.
The following did NOT help.
1. F8
2. uninstall > install
3. uninstall > manually remove all Corel folders including those in Common.
4. Norton Registry Cleanup.
5. Windows Restore
There must be a hidden Corel file somewhere.
Does Corel have an application which removes all Corel files and
Registry entries. (I'm afraid to touch the registry.)
.. Thanks for any help or suggestions.
Phil
