So what do I do to get off my fork if I am on one?
Btw, simpleminer doesn't launch for me, i'm new to this type of wallet, what do I do?
Well, not my favorite thing to explain ... because as far as I can see there's really no reason for yet another fork of a CN coin, but I'd rather people do things safely and correctly ... so to get on the new fork just delete all your blockchain/p2pstate data and re-open the daemon. It will re download the chain and you should be on the right fork.
Are you using windows? Simpleminer needs a .bat file to run it correctly, and a pool to connect to. you can mine from simplewallet solo mining unitl a pool shows up
