Hey I running minecraft 1.4.5 and all my mods are in the update and the server used to work. I lost internet for a while and just got new. while trying to start the server back up and everything when I click to enter it all loads as it should and the server reads that im there however I just get a blank screen with the brown block background and a done button at the bottom. when I click it I exit out of the server... I cannot find anywhere why this is happening ive been at it for HOURS.
