Error 2: 'First save the artboard before trying to upload'
First, make sure that the .ai file is saved on your local hard drive. If you are confident that it's saved, then the next step is to save it again by using 'Save As' Ai file. There are times that Adobe doesn't recognize that the file is saved so save it again.
If the problem still persists, then rename the file. The extension doesn't like the word 'untitled' in the filename so make sure that you rename the file and remove the word untitled and hopefully that will resolve the issue.
