Minecraft 1.8-forge 1.8 Crashes on trying to build worlds

Tyly · January 16, 2016

Hello,

I have downloaded and updated Minecraft and forge 1.8-11.14.4.1563.

After selecting to build world it will try, then close internal servers then shut down, and list the following report.

I have turned all my graphics down as far as I can.

I have read as many articles as I can, but none seem to fix my issue.

Thanks for any help, first time posting on a forum, read the EAQ, hope I did it right.

Thanks,

Ty~
