Hi Mikey,
I see in the log file it said cannot find the 'Screen_2&.bmp', may be you should create a Screen_2&.bmp in the workspace, and try again with the right ipj file.
Hope you can open the idw file in Inventor and change the Model to Vault to check everything is ok, and make sure the file can add to vault by inventor add-in. For the dataset, I mean could you upload the files you use, this will help our diagnosis, Thanks.
Regards,
Polo
