Set settings to default

Is there a way to set the settings back to default?

I'm trying to connect with a server, and I alwasys got: Too many users, but after some attempts I could log in.

Now I don't get that anymore, and i also can't login.
I only get:

Continue to login attempt 26...

It may be that i have changed something in the settings, but i'm not sure. Is there a way to 'reset' them???

Thanks!
