mechwarrior 4 mech packs

[pincopallo73]

Hi everyone... is there someone who knows how to make work the mech packs for mechwarrior 4 vengeance?

I have installed both of them, but when I start the game, the new mechs and maps are not available (in instant action... in campaign I already knew that they were not supported).

any suggestion? patch, crack or something like that?

thank you.
