Just installed a new version of the Ai v 28.6 and new plugin (version 28.x) but I am getting a blank screen and wont let me log into ArcGIS Online and I am unable to open any .AIX files.

Do I need to change versions?
EDIT: I was running a pretty old version of the plugin 3.2 and made a huge jump 3.7 that probably locked up may plugin
