Novo Mestro won't start

[R4L]

Yep. I get the zip downloaded and it has the dos executable and the readme, but when I click on the exe the black screen comes up for a split second and then disappears as if I didn't click on the exe. Does anyone know why it does this?

EDIT: Now it seems to not start up ANY dos executables of AGS games. I can't play QFG4 either!
