Slush's pool worker offline
At this point 2 TH/s is ok for small miners, 2 GH/s is crazy slow and 2 MH/s is probably not enough for the pool to even detect that you are mining at all. So that's most likely your problem.

Even the best gaming computers had to give up in 2013. Mining is now done on ASIC hardware. Computers are just too slow.
