Are you using a no cd crack, mod, or any other modification to the game files (after installation)?

Did you install on the 1.1 patch?

If you answered yes to either of these questions, your installation likely failed.

You should reinstall m2tw and start again, patching straight to 1.2

Umm! if your seeing capital letters and 'z' instead of 'ease' in the opening post I think the problem might be your end. There's nothing weird about sike49's opening post on my PC.
He was referring to 'please' being spelt 'plz' (need a proper 'rolls eyes' smiley here for me )
