Certain File keeps causing 'CorelDRAW X7 has stopped working' - any way of fixing file?

I can no longer open a file I want to use without a 'crash'.. Other files open and work OK.

I have used F8 on bringing X7 up..

I have completely removed the software and reinstalled it..

Still no good. I was thinking of trying to install on another computer and trying that but that would be a lot of work (and the other computers I have are Win10 64) whereas my computer in a Win7 (32)

It there a way to 'repair the file'? I have the installation CD

regards

Steve
