GameBrowser: Error prevented this game from launching

[totalhavoc 13]

I just installed GameBrowser, new MediaBrowser user, and I'm unable to get any games to launch. Just testing GBA games at this point. I read the other post with similar error from January but not sure if it pertains to my issue. Below is the log:

Any ideas on what I'm doing wrong?
