Can not connect to server edited to add more info : General & Trouble Shooting

I just resubscribed yesterday. I can not get xunleashed to connect. I start it, put in my name and registration code but the "play" button never pops up and after a while of waiting it will say can not connect to server.
I have tried several times and searched the forums and couldn't find anyone with a similar issue.
I am on a university connection, I am wondering if maybe xunleashed just will not connect from a university connection.
Thanks in advance for your help.
The exact error messages I get when I try to connect are
"Xunleashed servers appear to be down.."
"ERROR: Unknown protocol used, reporting...."

we no longer use registration codes. the log in for xunleashed and exhume is your forum account/password

That is what I was using what I need help with is figuring out how to get it to connect to the server.

if you re-subscribed we got the problem that it takes the server a few days to recognize your renewal for you to log into a program such as xunleashed or exhume

Let it patch to the latest client.
Then click on registration tabl. Enter your forum name/pass, Click Lock Key.

i tried reinstalling, i have let it patch every time, typed in my user info and locked it everytime, the problem is on the xunleashed tab it says click play and the play butten is not clickable then it says
Xunleashed server appears to be down
ERROR:Unknown protocol used
Reporting...

this is the version its patching to
