Aristois Fail to Launch
-
Go to
.minecraft/logs/
and upload thelatest.log
to something like https://paste.ee -
I'd assume this is the wrong log, since it's from you playing in a server. Since you got that error earlier something is probably blocking Aristois from being downloaded correctly, such as your firewall or an antivirus program. I can't help much except tell you to try disabling those things and reinstalling with the "clean" option selected.
