It should be obvious that we would only direct you to the FAQ entry repeatedly because the solution is in there. If you are having problems after claiming to have performed all steps in the FAQ, you either followed the steps incorrectly, or are lying about going through the process.
The account server has been operating without any downtime since the first of September, so any connectivity issues that you are encountering originate on your end.
That leaves the other 4 bullet points. MD5/SHA1 sums for the GSI and post-patched Tribes2.exe are in http://www.tribesnext.com/forum/index.php?topic=721.0
, so you should verify those were not corrupted during download or copying on your computer.
If the sums match, that leaves 3 bullet points. Affinity problems that result in an inability to see the server list or contact the account server are extremely rare (only two reported cases in the last 10 months).
If you rule out affinity problems, that leaves a firewall of some sort. Disable it, or add an exception for Tribes2.exe, and it will cease to be a problem.
In almost 10 months of answering support questions, we have never encountered a connectivity problem that couldn't be traced to one of the bullets in the FAQ. Until you provide concrete evidence that you can read and understand written text (which I doubt, since you PM'd me after I told you explicitly not to), I'm going to (albeit presumptuously) assume that you have not followed the FAQ.
If you desire real time support, connect to the IRC channel. It is helpfully listed at the bottom of every page on this forum. Be prepared to explain in detail what steps you have done so far before you join the chat channel.
