so when i try to play erebus (i have other mods installed too) it says i need a higher version than 1291,i need 1566,but when i try it with a slightly newer version,1541 it crashes,i guess i need to try the 1566 one,but iam not sure if its an issue,bug or just plain stupidity of me...for those who curious,here is the crash report
crash-2016-07-07_10.55.53-client.txt

EDIT: i just now installed the 1614 version,and still crashes,again,here is the crash report
crash-2016-07-07_11.17.54-client.txt
P.S iam experiencing problems with every forge above 1300,and the same crash gets reported

Hello,
I can't really make out anything from the crash report.
I would suggest removing mods until you find which one is causing the crash.
The version of Erebus you have is the latest and it does require a forge of 1566 or above (of which you have). Also try to remove Optifine and see if that is the cause.
Cheers,
Me.
