Backed Up 09 Engage files not opening
We did some trials with Presenter 13 with Engage files. On Engage 13's prompting we made backups to allow the backups to be opened with the Engage 09 version. However now when we try to open these backupped files in Engage 09 we get the following error "This project cannot be opened. Please make sure it is not already open in another instance of the application and try again." Can someone please help us. We cannot afford to upgrade right now, but we need access to change content in the engage files for our clients.
