@rahmat , can I suggest to either add your project here or send it to support. It will be very hard to answer this question as such. Maybe it got corrupted during the save. Please add instruction on how to create the case and the steps you are taking if you decide to do either of this. 

PS: Not sure how much data you expect to store and whether you have enough hard-disk space on your machine. 

Hi @rahmat 

Were you able to figure out the solution yourself or through support?

Please upload your project and instructions on how to create the case if you are still unsure.

Best

Hello @Andrew ,

Thank you very much.
