I had the Trial of Photoshop CS3 installed back in November, and recently the company I work for has gotten me a copy of the Master Collection suite to install on my work laptop. Problem is, I uninstalled Photoshop over a month ago, and it still says that it's installed on my computer. I tried using Time Machine and reinstalling it, and finding out how to "deactivate" it, with no luck. It just stops me at the Trial Ended screen and asks for a serial, which the Suite's cd-key doesn't work with. Any suggestions?
