Can't get into test server

I tried logging on to the test server today and i got a message saying this.
The instruction at "0x7470b439" referenced memory at "0x7470b439". The memory could not be "read".
What should i do?!?!?

I had that error, but it would eventually let me on if I kept trying. There is a solution that seems to have gotten rid of the error for me in this thread.
