Hey guys you did a great job on the beta 2! Now i´m interested in what you´re going to do now? Will you add new stuff to the generals or are you just balancing & bugfixing? Or do you just work on the challenge and the campaing or what are your plans right now?
Do you have any older versions too? Having the newest one isn't always enough, because they are pretty much separate things.
I think the launcher specifically needs 3 or 3.5 version. If you don't have them, you should still be able to install it even if you have 4.0.
