Shapes becomes invisible

Hi there
This is Ramesh from EFX Prasad, I’ve Mocha V.2.5.2 installed in Windows,
in fact I installed this particular version just couple of days back before that I
was with Mocha V.2.02. With the latest edition I’ve an issue where the application crashed in between the work and then I opened my existing workfile
all shapes becomes invisible but it shows all keyframes.
Any help pls.
