Okay. I'll bug the admin about it. Thanks for your help.

Title: Internal Error: Java.lang.NullPointerException Version: 3.1.2 OS: Windows 7 32 bit Java Version: 7u7 Description of Problem: I'm trying to log onto a friend's Tekkit server. When I do, I get an error message "Connection Lost Internal Error: Java.Lang.NullPointerException" This happens ONLY on SMP, single player works fine with no errors. I have tried everything I can think of (admittedly not much, I don't know much about computers), namely repeatedly completely deleting and reinstalling Minecraft and Tekkit, moving folders to new locations, and several other web-suggested fixes. Nothing has worked, and I am still getting the error message. I should mention that the server appears normally in the connection window and that the error appears to occur immediately after or during logging in; Minecraft shows "Logging in" but then goes to the error message before the world appears. The only option from the error is to return to the main screen. I'm sorry if this is posted in the wrong place, this is my first time on this forum, and I don;t know enough about computers to say if this is a bug or something else. I've pasted the entire error report below for the same reason: I'm not sure which bits (if any) are relevant. Thank you to anyone who can help me get this resolved.
