x3 instalation issue

Here's the problem:

- after win7 recovery I faced Corel (draw onyl, others - photo, trace ... run properlly) issues:

   - if I click the program icon, blank gray workspace with no sheet appears, buttons are non-active, menu is not responding. Program can be closed with win7 task manager only.

   - if I click *cdr file, program runs with several mistakes: slow, some buttons are not active, it behaves weird ... 

- I performed removal of  the program with win7 uninstaller

- I installed it again (with original DVDs and SN). The same problems occured

- Unistalled it again and installed previous ver.11, but the identical and the same problems occured

- I installed X3 to another computer, everything works perfectlly

Thanks for advices.
