[PC] Mass Effect LE: Can't start ME2 or ME3

Trying to play through the Legendary edition, and played through ME1 without any issues. Went to start ME2, I get the launching ME2 splash screen, quick black screen, then back to the launcher.

I've tried everything I can think of...uninstalled and reinstalled, updated drivers, tried running the MassEffect2.exe file instead, but it seems to just open the launcher. I tried starting ME3 out of curiousity, and got the same thing, splash screen, then back to the launcher. Anyone else run into this? Found a solution? Was really looking forward to playing through the trilogy again!

Attached DxDiag file.
