like the title says, i cant start monster anymore. its ending with the sentence: Process ended with code: 0 i dont know what to do it seems like i cant start any other mod either with the mym launcher. im on win 8 java 8, the latest verison of it. i updated since it as a recommended version.
i fixed my issue by installing java 8 update 11 and uninstalling java 8 update 20. i hope this helps anyone else who run into the same issue
i had something similar, java super bugged on me, i couldn't install a new update, i couldn't reinstall other updates, it would not run ftb launcher or mym launcher, and would just bug out alot so thats kinda unhelpful advice xD, yes i tried rebooting
Forge doesn't like some versions of java 8 some work, some don't but my best advice would be to downgrade to java 7
