Re: How can I tell the EA app that my Bioware folder has been moved?
Ok, this has been resolved. @holger1405 was correct - this was a Windows issue, not a Dragon Age or EA issue.
I moved all of the files from D:\Documents back to C:\Users\<MY NAME>\OneDrive\Documents, then deleted the D:\Documents folder, and then rebooted. Then I created D:\Documents, Run > %HOMEPATH%, right-clicked Documents > Properties > Location > changed the folder to D:\Documents and clicked Apply. This time it worked - I did not get the previous error message.
The files were not automatically moved over so I had to manually move them over. It took awhile to move the Bioware folder but once I did I ran EA, ran DAII, and the Load Game menu option was not grayed out, and when I clicked it I could see all of my previous Hawkes which had been copied over to D:\Documents.
This wasn't an EA/DAII issue, but I probably wouldn't have gotten this resolved without the help I got here, so thanks for that.
