Hi folks: I've got a *.MoCap project file that I created in 2011. My V2 software won't open it, and the V4 demo software won't either. How do I open/convert this project? Thanks, Michael

Is there any solution to this?

Did you ever get an answer?
I've got iPi V1 and have discovered that it doesn't work on my new computer. I've downloaded the 30 day trial of V4 and there appears to be no way of converting the many years of motion captures that I've done.
The fact you don't appear to have had a reply from anyone doesn't inspire me with confidence. So if I don't hear anything from tech support, they'll have lost a sale, as I won't be upgrading, I'll just run it on an old Windows 7 machine.

V1 is out of support for decade. There is no way to convert V1 project to a modern one, unfortunately. But V2 and V3 projects can be converted to the modern ones - just open them in the iPi Mocap Studio 4 and it'll suggest to convert.
