IDEA 14 Autopopup code completion not working

Hello,

with the new IDEA 14 my Autopopup code completion isn't working (The Setting is checked)

I get an IDEA Error everytime I wait for it to pop up.

11:31:03 NoSuchMethodError: com.intellij.codeInsight.template.CustomTemplateCallback.(Lcom/intellij/openapi/editor/Editor;Lcom/intellij/psi/PsiFile;Z)V (show balloon)

Thanks for your help.
