[Solved] Simhub won't launch, stuck on "Creating Window..."

RESOLVED: I just downloaded the latest Sim Hub installer and ran it over my old one and bam, fixed! (How stupid am I for not trying this before?)

I tried repairing some Windows files I found in an old post, but no luck. Anyone have any experience with this?
