Crashes upon startup when using forge

[deltahalo11777]

Hellooo. New here, I read the EAQ and didnt seem to find my issue. im running 1.6.2(installed with the correct installer) the only mods I have active are optifine(which doesnt work but thats not what im asking about atm), and jammyfurniture mod. Basically I had forge working and it was all fine and dandy, and when i went to install optifine it didnt work the regular way(putting the zip in the mods folder) so i followed the tutorial that EVERYONE, and i mean everyone said to do: go into .minecraft/versions make a copy of your 1.6.2forgexxxxxx folder, rename it, rename the 2 internal files, that whole deal, and then drag optifines contents into the minecraft.jar in the newly copied folder. Well that made it crash. and I know i did it right because ive done it before. Well I was like, okay, leme just delete that copied folder and reinstall forge to refresh everything (even though i didnt touch the original forge folder, just being safe) and then just forget optifine and use my other mods. well now it just crashes after i click play, even when i have the fresh version selected. Any help would be appreciated, ive done research and couldnt find it, and i could be missing something simple here too, im kinda new to this. And yes thats absoloutely everything ive done as far as modding goes so i havent messed with anything else. Heres my log:

This did not work. Either you have modified the minecraft jar file (if so run the forge installer again), or you are using a base editing jar that is changing this class (and likely others too).

Reading the logs...

 

[deltahalo11777]

thing is, i kinda dont want to mess up the game, it also says DO NOT RUN. So if i can get confirmation that it wont mess anything up ill try it, but i want to know why it all of a sudden doesnt work... and no dude, i dont have optifine now so weird

[deltahalo11777]

like it was working perfectly fine before and for no reason im getting this error now, and i dont want to mess anything up by further changing things, im wondering if anyone can provide any info on WHY this has happened and if it will be okay to just proceed with the option the log provided, since it warns against it.

[LexManos]

You've edited your jar, for some reason.

Don't do that. Clean your minecraft jar and run again.

[deltahalo11777]

I reinstalled the entire thing. Its all fresh. thats why im so confused.
