Thumbnails on CorelDRAW X3 disappearing XP 64bit

Hello, happy new year.

I have a question about CorelDRAW thumbnails. I have a Windows XP SP2 x64 system, CorelDRAW X3, love it, but every time i restart my PC, thumbnail previews disappear from my .cdr files. Then I go to Add/Remove programs and fix it, but it resets every time. Anyone knows permanent fix?
