wow, must be beacause of the new dynamic image, thats all ive changed and its server side.
servers going down for a few mins so i can reboot
I don't think that should freeze the client. There could be a few flaws in this, but shouldn't it only update the picture when the server starts, and exits? If so, that shouldn't be the problem. Now, if it does freeze the server, then that could freeze the client in it's connection process, but that seems unlikely since I was still able to register, it just froze afterwards.
The problems was most likely because of the way he updates the dynamic image with server status. And it has to be updated everytime a player joins/leaves because it displays player count.
The game freezes because he is using a method that sends a http request to a webserver and the game will freeze until the server responds.
The image and user data are stored on two different servers, so that's why you were able to register. What must have happened is that my server (which the image is on) went offline for a few minutes.
So I would recommend finding another way to update the darn image xD
