Panels.DLL

Can anyone help ? I have just got my P.C. back after having a new hard drive installed. Before it went to the repair shop 2004 was working perfect.
Now when l try to install 2004 it installs no problem, but when l try to start using it l get hit with a caption which says;-
Fs9 hascaused an error in PANELS.DLL
Fs9 will now close.
If this problem continues restart your P.C.
I have of-coursed tried that, and un-installing 2004 twice with no luck.
Be gentle with me guys, I'm computer illiterate.
