REINSTALL THE PROGRAM IF DOES NOT WORK FIRS INSTALL THE PROGRAM AND THAN SP2 GOOD LUCK CAN BE FILE CONFLICT

SP2 did break a few older programs and does not play well with some older hardware.

I doubt that the CD version of SP2 will make much of a difference.

Start by downloading and installing the latest drivers for your motherboard and video adapter.

Next, check the software manufactures web site for patches and updates.

3rd, run Windows Update.
Some of the SP2 problems have been fixed by patches.

Still having problems, please provide us with more specifics:

Amount of system RAM,
Free HDD space,
Video card,
Specific software and problem description.

Any other details that you can think of.

SP2 is a upddate for wx and acts an newer version of OS so reinstall the program

Had GREAT LUCK with initial install of SP2 ! Every time (5 BOXES) had to unistall and reinstall to get it to play well with any program ! Did not like MS or any DOS based programs (and most normal windows) ! Second install work favorably and with all the (MS required) patches started to work like WIN 3.1 ! Defragging / chkdsk / anti-virus / anti-spyware is running better than 2000. So backup your data, uninstall SP2 and reload SP2 then patch the H out of it until MS says you are up-to-date !
