bindException when run via "activator ui"

[CodeCombiner]

Hey Adrian!

First of all thanks a lot for nice seed project!
I have an issue when running all projects on Ubuntu 14.04
When I try to run via "activator run" everything works fine but when I try to run via "activator ui" it asks to addSbtPlugin("com.typesafe.play" % "sbt-fork-run-plugin" % "2.3.9") and then compiles well. But when project starts to run and netty tries to deploy, then only 1st named or 1st compiled project deploys successfully and works fine but console gives following error concerning 2nd project deployment:
