--- Comment #19 from Sebastian Loncar sebastian.loncar@gmail.com --- After some more tests, it seems, using the native dll will not work. Maybe i did a mistake while testing before.
Summary: Patching the source of imm32.dll is the only working way to get the steam community working (and with that, the muliplayer mode).
