i own the game and activated/play it on Steam. bought the kombat packs from here, but steam keeps asking me to install the original game before i can install the packs. anybody else dealing with this?

Def gonna use this site in the future if I see any deals I like. Quick delivery and a fun game to boot. Works much better since the XL update.

this is the full game ryt?

Can this game be activated in China? Looking forward to reply, thank you!
