Sending Client Issue not starting

I used to play on PMU a lot over the last few years and had the urge to get back into it so after I tried using my old client and finding out that it was outdated I downloaded a new client, and made a new account. After doing this I tried to login and I got stuck at the sending login info message for about fifteen minutes before I decided to start looking for solutions. Is it possible that the main site has changed? Is this still the site? http://pmuniverse.net/

Thank you for taking the time to read about my issue and any possible help.
