February 23, 201510 yr One or more of the mods you have installed is playing a sound incorrectly and crashing. Sadly these issues are hard to track down. If you can reproduce it you can try removing mods one by one until it stops. I do Forge for free, however the servers to run it arn't free, so anything is appreciated.
