Thanks Milli,
can you specify which .exe you've selected in RP -
DCS, Launcher or Run, and are you using any option in Launcher tab?
I've got DCS on Steam, but start the game without it (don't know if that does any difference, but I've read that DCS is most stable without).
Didn't know 2.0 Alpha was compatible with RP!
Cheers,
Tommy
