Thanks Trev.I just do it like this.And Enter key instead of OK button and it works.BTW I've got an answer from Corel:

Thank you for your e-mail. Please close PaintShop Pro X2 Ultimate and do the following:

Update your operating system and hardware device drivers; please go to Windows Update and get all the critical updates released by Microsoft. It is very important that your Windows is updated:
http://windowsupdate.microsoft.com/

Then please visit http://search.microsoft.com/ then manually search, download and install the following updates:

1.) DirectX End-User Runtime
2.) Microsoft Visual C++ 2005 (x86)
3.) Microsoft Visual C++ 2005 SP1 (x86)
4.) Microsoft Visual C++ 2008 (x86)
5.) Microsoft Visual C++ 2008 SP1 (x86)

Afterwards, reboot your computer. Once restarted, check if you are running the latest video drivers for your video card. If you have an older version, download the latest video driver (a reboot may be required).
