after this crash I'm not able to enter the world again.
Crashreport: crash-2016-09-13_14.58.27-server.txt

You are using wrong version ae2stuff. Crashlog says you have regular ae2stuff mod, but applied energistics is rv3. Install ae2stuff rv3 version

That's right I used a non rv3 version.
I tried it with the right version and it worked fine.
Thanks for help.
