Internal server error (technic profile problem)

[mrthesplit22]

Sorry for the repost but my previous post got all complicated and I wanted to start fresh and I could not find a way to delete it.

Launcher/pack Version: Launcher version 1.0.1.3/ Tekkit 2.1.1

Operating System: Mac OS X

Version of Java:

Description of Problem: When I try to log in it says "internal server error".

Error Messages: http://pastebin.com/4Zydimpg (sorry for not having the console messages for when the server started up but everything is normal for when the server starts up)

Hello,

When I try to log in to my tekkit server it gives me the message "internal server error". I can connect to any other tekkit server and it works fine. I have tried to login in with my friends PC instead of my MAC and I have the same problem. All my other friends who have MAC's or PC's can log in (example in the console log "narshredder99" was able to log on). As you can see when I "mrthesplit22" tries to log in it doesn't work. It's not my launcher because first I have deleted everything in the directory and reinstalled it and like I said previously I tried on my friends computer and it still didn't work. We have deducted that it's probably something that has to do with my profile. By the way I can go on a normal server with the vanilla minecraft launcher.

Any help would be greatly appreciated!

Thank you!

MOD EDIT: Don't do that.

Try deleting the file world/players/mrthesplit22.dat

See if that solves it as there may be a buggy item in your inventory, ive had it happen to me

No Problems. It happens to me when i spawn in an item with the item id and I get it wrong. So always double check the item ID before spawning it in :)
