Illegal Argument When Trying to Open Tekkit

[Skulluk]

Launcher Version: 1.0.1.3

Operating System: Windows 7 Home

Java Version: Java 6

Antivirus Program: none

Description of Problem:

I login and try to open tekkit but when I do it just gives an error report. I've read through the error report and it says that there's a slot arguement or something with the ender chest and block rub sapling or something like that. This isn't an ingame error, it won't even open the main menu of Minecraft. This is has been a problem for about a week and a half.

Not sure if this is a launcher bug or a Tekkit bug, so sorry if I posted in the wrong area.

[Torezu]

It's really a little of both. I'm guessing you tried to update Tekkit, and something in the config files didn't overwrite correctly. I would really delete your .techniclauncher\tekkit folder and reinstall. Make a full backup of the folder, somewhere else on your hard drive, before doing so, just in case. Among other things, your waypoints and video options configs will reset. You can copy your waypoint files over from the backup after you reinstall (tekkit\mods\rei_minimap, I believe). I also highly recommend removing Java 6 and installing 7, 32- or 64-bit depending on your system.

[Skulluk]

Thanks. That fixed it.

Word of advice: Get some sort of AV.
