It sounds like you maybe still have a UDP port problem if your browses are not working. However, this should not keep you from entering a room you are able to find on the list.
Also if you enter a chat room name into the Filter bar you should be able to gain access that way.
I dont like that some folks cant get into our room, we try very hard to make that available to all users for help, fun and chat.
That is the current name and although I have not been able to locate the problem with some users entering its not isolated to just our room either.
I hope that you can find us soon there, and until then I will continue to help you here as much as possible
