Build issues with Gradle Android studio 0.2.1 -

i've updated android studio version 0.2.1 , since when open clean new project , try build + run following error:

abnormal build process termination: error: not find or load main class files

do know how can avoid it? doing someting wrong?

i managed bring android studio working state. gave on 0.2.1 update , reverted 0.2.0, know worked fine. here's how did it: uninstalled android studio ( add/remove programs ), deleted contents of \android\android-studio ( except sdk folder , sdk manger.exe ) , downloaded , installed more stable version bundle right here: http://developer.android.com/sdk/installing/studio.html#updating after that, should able reopen projects working on, without encountering other errors. luck!
