Hello there, this is the first time i'm posting on the forum, and I was wondering if someone would be able to help me out with a problem.

I am running the client on a windows 7 64 bit computer,
and every time i go to sign in, it encounters some kind of error, and I have to close the program.

I used to have no problem signing in when i first joined up to the playroom a couple of months ago.
But I think there has been an update since then, and I haven't been able to sign in since.

Is there anything special I have to do to get it to work?
