Photoshop CS2 Problem

[Hai Perso Coyone?]

Hey everyone,
I just got the trial version for Photoshop CS2. I have Photoshop CS installed and I just wanted to try out how CS2 was. When I fire up Photoshop CS2 now however, the splashscreen loads up and after it says Scanning Plugins...the program just hangs...I have Photoshop CS installed on my Local Drive (C:). I decided to install this version on my portable 400GB HDD...could it be something in my Registry thats messing around? I don't know what to do...I can't try out PSCS2 and now I only have PSCS to look to...any pointers anyone?

Cheers all,
Ashar

No one?

Can't honestly say I know.  I doubt it's the registry.  I never install programs in their default locations.  I have CS2 installed in C:\Core Programs etc.
