Okay, so I need help, I can't find the password for my worker. I mine in slush's pool, and I mine with GUIminer. Even if I use my account password it says that my worker is offline.
As was asked of you in the previous thread... what gear are you using? Are you trying to mine BTC with just your laptop/desktop CPU/GPU? If yes, just stop. You will make nothing. You won't even make the pool's minimum withdrawal after months of mining.
I think it's CPU/GPU most likely with GUIMiner being mentioned. In 90 percent of cases with GUIMiner this is what's happening.
I highly suggest doing some ROI math. Sadly for most you will lose money mining with CPU/GPU. It just costs more then you make.
