I use Minecraft Technic Launcher to play minecraft and as soon I add the Flans Mod in, the game won't start anymore and I get this txt file in my crash-reports folder.

Applied Energistics 2 is trying to register a dimension with ID 2, but that ID is already taken. Check if you can configure it to use a different ID.

how can I change the ID? I´m not a expert in configure programs.

Depends on the mod. Refer to it's documentation or ask the author.

Das ist eine Jar Datei. 

Da kann man doch nichts ändern?

Please keep this forum in English.

Mods usually create a configuration file in the config folder.

Ok, i will give it a try. So I can choose every ID except of 2?

Well, it tried to use 2 but that was taken. You can try another (-1, 0 and 1 are taken by the vanilla dimensions) until you find one that is not taken.

I have two screenshots of the flan mod files generated in the config folder but I see no IDs.

Why are you looking at Flansmod configuration?!

 

 

Oh my bad, ok I got it, so Applied Energistics 2 was a config file.

I changed it to -1 and it seems to work for now.

I'll contact you if I get any errors in future.

First I'll try to fix it myself of course.

Thank you for your help.

Don't use -1.. That should crash as that's the nether (or the end, I don't remember).

It changed automatically to 3... very mysterious o_o 

Well at least it work now, thanks again.

Ah, it might have -1 as a special number meaning "choose automatically".

yeah propably.

It's actually so simple to fix it, you just need the "know how" ^^

And as I'm programming in shool, coding isn't very strange to me.
