iMac Crash, Need Help A.S.A.P.?

[KMW]

Okay, so I renamed my iMac last night, including its local file name. Today, I went back and tried to put it back the way it was, both name and location, and now it has crashed and I have a lost a substantial amount of crucial data. I have a Time Machine, but it seems corrupted, too. Does anyone have any suggestions to fix this predicament? Serious answers only, please.
