[MESSED UP REALLY BAD]

SOMEONE PLEASE HELP ME.
I do a series on my channel and I need this to work. I'm using a version of yogbox you can't get anymore (for 1.5.2) and I tried to install optifine and without thinking I didn't back it up and now I get a crash everytime I try to start it even though I've restored my minecraft in the bin
