Error: Specified argument was out of range of valid values
Trying to save my presentation last night and I received this error.
When I clicked OK, the Story View went blank - no slides were visible. Nothing I did worked to save my presentation. I couldn't save it to the original location, or to another location, and I couldn't even try to open a new instance of Storyline and copy/paste so I didn't lose my materials.
Eventually I had no choice but to completely shut down Storyline, and when I reopened, everything I'd done since the last save, and some things I'd done prior to saving, were gone, including several minutes of screen recordings.
Has anyone encountered this error, and is there anything I can do to retrieve my data?
