i can manage to install and run aim triton easibly, but the problem is when im trying to log in!

when i enter my login details and press login, it loads up and then it says "validating..." this is where the problem comes in: it makes me wait for hours (exaggeration- more like 15 minutes or so) and then it says i cant connect or something. this has nothing to do with my internet because i can get in normal aim without any problems, but i want to know a way to get around this; and a reason why its happening.
everyone i know can get it working without any problems!
