A problem that has popped up..

[Spunky2000ca]

For some reason whenever I play, I get killed, no matter where I am, what server, whatever amount of health, anything. I die.

I do have the new version (2.3rev3 I think)
I also have the version 2.2, and 2.1.

I've used the 2.1, 2.2, and the 2.3 Version (in separate directories) and I still have this problem..

This was also posted in the General Forum, but nothing to identify or solve the problem was said.
I've lost 100g on Graal2001 trying to fix it. Any reason why it's messing up like this?
