Cant open previously generated model

After solving my mesh on RC i saved the project. When i reopen it, it seems i lost my calculated mesh. Im not using the demo version. its a subscription. Need help asap on this cause im rebuilding my mesh for the 3rd time and it takes at least 3 hours. Thanks in advance


Did you try to reprocess all data in new project? Or did you used old one. 

Please clear your cache, and reset application. (press Shift key when starting the application) 
Then reprocess your all data in new project, and save it. If the issue persists, please contact directly our support via contact form.
