So, this is what happened. Lately I got into Tekkit again and have been playing on this one server. (NO IP TO ANYONE) I got kicked when I jumped into my private river and started flying with my swiftwolf ring. The error I get is: "Internal Exception: java.io.IOException: Not in GZIP format".. Before you ask, yes I have reinstalled it. Yes I can connect to other servers. When I try to connect on my sisters computer I get this error: "Internal Exception: java.util.zip.zipException: Not in GZIP format".. What the heck does this mean? How does one go abouts fixing this? Thanks!
