Ok by applications I mean browsers..you may be asking how I'm here...my computer is only letting me open up IE (I'm on 8). I have FF/Opera/Safari/Chrome/IE8/IE6
Here is what happens for each (quoted directly if needed)
FF-The application failed to initialize properly (0xc0000005). Click o OK to terminate application
Opera-Failed to load Opera.DL because: Invalid access to memory location
Chrome-Whoa! Google Chrome has crashed. Restart now?
I should note that I'm on Windows. The most recent changes are that I put a password on my computer so you have to login as a user to get on (I'm the only one besides guest) and last time I shut off my computer I held in the power button I'm on a laptop).
I really do hope I gave you enogh information. I even tried reinstalling FF but to no avail.
