Try deleting techniclauncher/tekkit to reinstall tekkit. You can keep saves and texturepacks if you want.

[Magister]

it is a conflict with the item ids, you can just go into the tekkit folder and change the numbers in the config files, looks like the conflict is enderchests and ic2, but chances are you may have more

you can try deleting and redownload as suggested but the error could occur again or occur with other items

[Skippy12]

Thanks guys. Deleting and reinstalling does not work.

Magister - I have no idea how to access the config files or what I need to do once I get there - can you explain further please?

[Magister]

start menu, in the run box type %appdata% press enter a window should open

open .techniclauncher

open tekkit

open config

open the config file in that location that belongs to the mod causing the issue and change the item id, can be opened in notepad

a way to find conflicts and test for open id numbers that can be used

start menu, in run box type cmd

in black cmd window type cd %appdata%/.techniclauncher/tekkit/config press enter

type find "NUMBER" *.* press enter

this will search all the config files for any line containing the number you enter in the " " and display it, and the " " is required

[DarthDavis]

That will not let you on most tekkit servers though, right?

[Magister]

you should have no problem joining servers, some mods care about the ids and if they do you will get a message about the item ids not matching the server, but i havnt had an issue with tekkit when ids are changed

also when you do the first run with a tekkit server some of the mods assign ids at that point from a range

you can test it by first running a server and then removing the configs and doing it again, you will notice differences in some of the mods configs

also it makes it interesting when trying to move world saves from one server to another server that has different ids

[DarthDavis]

Good to know. Thanks

[Skippy12]

Thanks for the suggestions guys. Still locked out at this point. I've tried the following:

• Changing the block ID for EnderChest or/and Rubber Tree Saplings (both are set to 241)
  
• Deleting the EnderChest block ID to reset to default
  
• Deleting technic and minecraft launchers and re-downloading fresh
  

When I change the block ID numbers (to 251 - after checking that was open using Magister's thread above), the new crash erro info I got was as follows. Any further suggestions you can offer will be great appreciated.

Cheers

[Magister]

you get that when you try and start it or after you have gotten into a game?

[Skippy12]

That's the message that comes up after the Mojang loading screen, when you would usually get the main game menu (Single player, Multiplayer etc)

[theprolo]

I'm not certain, but I think clearing the cache usually fixes that issue.

[Skippy12]

how do you do that please?

[theprolo]

Options in the Launcher. Press "Clear Cache" and it should clear the folder and reconfigure everything.

[Magister]

clearing the cache can be done from the launcher, should be in the options menu near the login

it will require you to redownload all the game data afte

java.lang.NullPointerException

generally points to duplicat item ids, when you change an id make sure you dont change it to one of a vanillia item as it will not be listed in the config files

[Skippy12]

Thanks very much once again guys, I'll give both of these a go and let you know what happens.

The help is greatly appreciated.

[Skippy12]

Thanks very much guys - clearing the cache did the job - I upped the memory at the same time and I'm back in the game. Thanks loads for your time and help.
