Oh boy, I think I really messed up something big time. I was trying to clean up my system fonts via Font Explorer. So I did the "Clean system fonts" in the Tools drop-down. When I restarted and came back, all my fonts were changed (icon fonts, menu fonts, etc)...but worst, I'm just beach-balling and my screen is flashing back and forth from grey to my desktop image...constantly back and forth. I can't click on anything, I can still see my desktop files/folders, and I can see the top menu bar but my machine is freaking out. I'm not a very technical guy when it comes to Macs so I really need someone's help. As of now it seems that I literally can't do anything. I can access the files on my MBP via an old iMac I have if that would help. Also this is a work computer but I work remotely from headquarters (about 3 hours away) so I'd love to get this resolved myself. Please tell me there's something i can do.
