Server error: Bad compressed data format

My info
Os: windows seven
Architecture: x64
Java version and architecture: "6.0.150.3" 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.

 

Try redownloading the craftbukkit.jar . By bad compressed data format, it could mean your download of the jar was bad/corrupted.

 

When craft bukkit is redownloaded nothing changes. Although when I took my laptop over to my place and tried connecting to it off my own router I was able to join and stay on. Im wondering if it doesnt have something to do with my freinds router.

 

Did you say you were having the error or both of you were?

 

I would get the error but only when I was using his wi-fi. when I went over to my place and used mine it worked fine.

 

Might be an issue with his Wireless. It could be interference or something of the sort. I guess its fine if it works now.
