My info Os: windows seven Architecture: x64 Java version and architecture: "220.127.116.11" 64-bit Wrappers: none Craft bukkit Build: 818 When ever my freind and I try to log into my recently moved server we would be able to play normally for about five seconds then we would lose connection. It would give us an error screen stating the following. Connection lost Internal exception: java.IOException: Bad compressed data format We are both playing on the same router as the server runs on. The weird thing is when my other freind joins on his own internet he is not disconnected at all. He says that when playing he does not notice anything different with the server. I have found that other post about this problem state that it is a corruption in the save but I feal as though this is not the case, since my freind can join. I appreciate any information that can leed to the solving of this problem. Thanks.
