I installed LimeWire a couple of days ago on the recommendation of a friend. Soon thereafter operating files for MSOffice and Adobe Photoshop disappeared from my system, as did lots and lots of my extensions. Now when I try to launch Photoshop, I get a "null" response, I've lost use of my cd drive, MSWord is missing all of its dictionaries, and my OSX system keeps on saying system resources are missing.

What the hell did I do wrong? I'm on OS X 10.2.8 and was using Adobe Photoshop and MSOffice versions given to me by a friend, serial ##'s provided by serial surfer four years ago.
