First off, you can edit posts. No need to triple post.
I don't really think that you read through all the alternatives and actually tried/checked what the thread suggested?
If the server is up and working fine for us, but not for you, it should have something to do with what's stated in the posts of that thread.
Uninstalling the game / reinstalling shouldn't make any difference at all if the game used to connect to the server just fine. It could be something temporary though, and waiting things out sometimes do the trick.
