STAAD MODEL DOESN'T OPEN BUT OPENS IN EDITOR

My perfectly working STAAD model file suddenly stopped working while updating in the editor. 

It opens in the editor but the model doesn't open.

I have tried reinstalling the application as well. No luck yet.

I use the below version.

  •    Thank you for your prompt reply and the options.

    I tried both of the options you have mentioned but it still doesn't work. The file is processed fully but fails to open. It is minimized at the taskbar and doesn't maximize the STAAD window as well. See the below image.

    Actually, the same file opens on another PC. And I also found out that none of my previous STAAD files opens now.  

    I also tried with updated STAAD.

    Do you think this is the issue with the PC or something related to STAAD application?

    Thank you in advance.
