I checked the archives and there was nothing so hopefully this hasn't been asked before,

My PS (7) has been working fine until about an hour ago, now everytime I try to open a file the entire program closes. It hasn't just happened once it happens everytime now.
Does anyone know what's wrong?I uninstalled it and installed it again but it's still not working.

eta: lol!so it fixed itself!it turns out some pictures I took last night are devil pictures, I tried to open them in firefox to upload them to imageshack and it completely cleared all my preferences in firefox.
I deleted them and now everything works again.
