The auto-patching screwed up for GSB yesterday. It was a typo. Sorry!
Anyway, it’s fixed server-side, so you just need to re-grab the patch, here is how to do this:
Delete this file:
\my documents\my gamesgratuitous space battles\patches\GSBPatch156.exe
Delete this file:
\my documents\my gamesgratuitous space battles\web\up
Then re-run the game.
The symptoms for this bug are:
1) An error “The program cannot start due to a program incompatibility…” or similar
2) the downlaoded patch seen above is only 2k in size…
