ive got the same problem.
I think it has to do with a Patch launcher. i restarted my comp and got a weird message when i tryed to repatch saying somthing like the patch server is down. then i got the same message.
For it to be a spec problem it means we are not up to date with the current version.
For you, i say restart your comp untill it patches. for me, a New solution would be epic cool
