I can't execute android app with intellij

HI. I tried the "Hello Kotlin" sample project from http://blog.jetbrains.com/kotlin/running-hello-kotlin-on-android . I fixed all error messages and it compiles well. But when I execute it with intellij, It stops with "java.lang.ClassNotFoundException: com.example.HelloKotlin". Is there something I missed? I'm using Intellij 122.746 and kotlin-plugin 0.4.160.

The fix is this http://devnet.jetbrains.net/thread/439551?tstart=0

Works fine. Thanks!!!
