Synthesis "could not load robot (file location) has it been moved or deleted?"

I just exported our 2016 robot from inventor and directly into synthesis. When I loaded into synthesis I got the error “could not load robot (file location) has it been moved or deleted?”. There isn’t anything suggesting what could be wrong. Here’s the exported file in case someone could look at it https://drive.google.com/open?id=18J9WCJO07LjPb0C0MS8k9m5j8uUAuShG
