Hello there. I'm new here. Well ok, lets not get off-topic, I was replacing some files on my mac, when the program which replaces or copies or what ever stopped responding when i was replacing some files. I tried to close it but it wouldn't close. I went to the force quit menu and saw there was no copier or anything just Finder. The finder was selected and im used to click cancel and i force quitted finder accedently. Everything went wrong and i can't see my desktop, the finder doesn't work and my mouse lags... I can't relaunch finder i have tried really much. PLEASE I NEED HELP!
