Cannot use Save As function

Hi everyone,

I've been using CorelDraw products with no issues for about a year now and have come up against a weird one, hopefully you might have some advice.

The 'Save As' function does not work. It is not greyed out and can be clicked on as normal, but the Save window (where you can change file version and file type) never appears. The regular 'Save' function works fine i.e. I can overwrite/update existing files but cannot create new save files.

This also applies to options Save as Template, Export, Export for..., Send to, and Publish to PDF. As I said, the sense I'm getting is that it's having trouble creating new files.

This first started after opening a file from an external company that came up as having "bad data that may not load correctly".

Any info or pointers you might have would be really appreciated.

Thanks.
