Corrupt File

I'm sorry that I haven't been editing much lately. My computer crashed due to a corrupt file, and I can't fix it yet because I don't even have access to safe mode (my computer doesn't even give me the option... even if I force it to shut down). Until my father comes back from his business trip, I'll have trouble editing. I'm currently on my laptop and I'm lagging badly. I definitely can't play TT for now. Oh, and the new editor is great.
