I use Mac.
If I try to export as JEPG it not let me to do, gives me an error: it seemes the file is open in other application. But it is not true.
I've just tried to disinstall and reinstall the application, but nothing changed.
The same license is installed also in one other Mac, and there the problem do not appear.
Someone can help me?
Are you still having a problem with this? I've seen it happen before too. For me mostly on Save. Sometimes I use CTRl_S and save. Or just wait and come back. It seems like after I close a file there is a lag to FW knowing it's not open. Does this happen just on export? Perhaps try giving it a different name.
