Cannot acess any other server than Graal Kingdoms?

[Elizabeth]

Ok. So I was on Graal Kingdoms, and decided to go to Unholy nation. I opened my server-list and I doubled clicked on Unholy Nation. So when I did, it brought me to my login screen, and a message occured saying " The connection could not be established! Check that the internet cable is connected and the firewall is not blocking Graal. " So I click OK and I log in. When I log in all the GFX is messed. It happens all the time. I don't think it happens to other people. I don't reallt know.

Then, Say if I'm playing Graal Kingdoms, It will turn a see-through white, and it says "Graal client has stopped working!" . It searches for the problem, and it says "End program". So it makes me exit graal.

So, the only server I can access is Graal Kingdoms. Nothing else will work.

When I open PM's, it says a bunch of random numbers and a few other things. I end up having to open task manager and end graal's process.

This only started happening when we got our new computer- which has Vista on it.
