      I have updated aptana to the latest beta version available (Aptana Studio 3, build: and editors are not works anymore.

      Error title:
      Could not open the editor: The editor class could not be instantiated. This usually indicates a missing no-arg constructor or that the editor's class name was mistyped in plugin.xml.

      I get the following errors when open *.txt files:

      I've tried to cancel the latest update but this also gives me error:
