Having received this error code all day... and Googling for solutions I was banging my head against a brick wall.
Someone else on this forum had same issue but a moderator with industrial aggregate in his vagina could only complain about grammar. Tosser!!!
Anyway... if you have Bullguard installed (like me) this was causing the issue. I had to uninstall it completely to get the launchers version check to go through. Otherwise I received the error in title every single time.
No amount of switching firewall off and running program as administrator would work. I had to completely uninstall Bullguard.
Right now I'm installing the game and hopefully no more problems.
