Importing and Exporting Mannequin A.R.T.v1

A few things are happening when I use ART to animate the mannequin. First when I load it I get this error

Then I have to find the file in my directory.
Once that is done and i finish the animation and export it using ART, i am unable to save the file

Then if I close Maya and try to reopen the file that I saved before the export I get this error that continues to loop when I hit continue

Please help. I am trying to learn the software and am having a hard time trying to work around it instead of using it.
Thank you.

It’s ridiculous that they provide no support for a tool they suggest using.

I fixed fhe problem by copying the Mannequin_export file from the artv1 folder (inside projects) into the “scenes” folder of my maya workspace
