error: Microsoft Visual Basic for Application

Since yesterday and from my perspective without any reason, I cannot longer use Endnote X4.0.1 in Word. Every time I push a button from the Word AddIn bar, I get the error message “Microsoft Visual Basic for Application: file not found”. I already uninstalled Endnote, Word and Visual Basic for Apps, seperately and in different order, but nothing works.

Hope somebody can help me.
