I opened a ticket with support and it didn't seem to help. I reinstalled several times, I moved the game from my solid state hard drive to my disc hard drive, and the same thing happened. It seemed that all was lost! And then, by chance, one day I launched TF2 from steam after I had tried to open SC2...and you know what? SC2 opened! It opened up along side TF2. My mind was boggled, to say the least.
Anyway, that's how I've been working around my issue since about August. I figured it would change up once HotS came out, but I just got into the beta and the same thing happens with this launcher! I figured it was time to air this out in public and see if anyone has any idea on what might be going down.
