Photoshop CS4 crash, won't open anymore

[xwinger]

So I've had photoshop CS4 and adobe master collection on my macbook since last december. They always worked perfectly until today

today I was working on a Powerpoint for school using Microsoft PowerPoint 2008 for Mac. I was editing a picture in photoshop to use in the pwrpoint and photoshop just froze up. I force-quit it and then went back to my powerpoint. My powerpoint then closed too!

luckily i saved just before, and i opened my powerpoint up again

but when i clicked on photoshop it bounced a few times then said that an error occurred and it closed. this error just repeated. I then tried adobe illustrator and it crashed before opening also. So I uninstalled CS4 Master Collection. I reinstalled Photoshop and it still crashed. looking around the internet told me to turn off airport and disable internet connections but when i do that, it loads the blue loading screen then says Could not initialize photoshop because there is not enough memory (RAM). This is very weird because I have never ever had a problem with low memory (I have 4GB)

so I closed everything except itunes and opened it and it gives the error message "Photoshop quit unexpectedly. click to report, blah blah, relaunch..."


so now i am freaking out because i cant get it to work and my project is due in 23 hours

any help will be appreciated


System:
13 inch aluminum macbook, late 2008
2.0 ghz processor
4GB RAM
500GB HDD
10.6.2

remember I was running powerpoint and photoshop at the same time

It sounds like the Photoshop preference file(s) might have corrupted. Try moving it/them to your desktop or deleting and launch Photoshop. You can find those files in: Home Folder > Library > Preferences. Search (Command-F or File > Find) for "Photoshop" or "Adobe." Make sure the the "preferences" folder is selected when you search.
