I have problems running minecraft with this mod. I installed only Alex's Mobs and at startup it gives the developer console and: "Minecraft closed with exit code: -1". I don’t know what to do, no extraneous modifications are installed. Has a crash-reports. Crash-report attached.

I have the same problem.

У меня такая же проблема.

I can't find solution to this problem...(
