Indesign files won't open

[LeonardFeehan]

Got a new iMac and tried ot open an Indesign file but got this warning ---

This file is already open by another user or another application. This file may be stored on a network server and cannot be opened until the other user closes it.

What do I do to fix??

I got it to work by uninstalling and reinstalling InDesign

All good now 🙂
