Well........ I have been using Adobe reader 5 for a long time.
Last time I opened a PDF document I got a popup asking to upgrade to Adobe reader 9.
Like an idiot I clicked ok.................. After the download and install was completed none of my previous PDF files would open

Didn't know what to do ....so I did a system restore and the old files opend ok....however now I can't open new PDF files, like something posted on the message boards. System freezes and the only way to get thawed out is to do the Control Alt Delete thing.
Using XP pro
Anyone got any

ideas?
Cheers
