Symptom:
AME will launch and open the Prproj file however once the project is open, it will fail to read XMP file (there is no failure present in Curator or within AME however it will just be stuck reading the XMP file)

Resolution
To resolve this issue, the user will need to remove any sequence markers and then export via the Curator For Adobe Plug-in.
