I am having the exact same issue. At first, I just thought it was the campus network I am on, but now that I see this, it helped me realize that ever since the last patch my games have been going incredibly slow, I get disconnected a lot, and much of the time, I just can't play. I, too, have created basic practice games with just bots and have been disconnected from them.
Now, if this is related to the patch or an Adobe Air patch, I don't know. It could be some wonky thing with my computer and the patch. So, I join the original poster in a plea for help.
