I'm starting a new project based around some development work with Lectora Inspire 18. After installing the program, I can't seem to get the template or sample file sent over by the client to work correctly. The message I'm receiving (soon before it crashes) is:
WIndow Title: Error creating window!
Pop up body: Invalid Window Handler
From this info, could someone determine what is leading to the crash here? Maybe it has to do w/ associated (external) files that I need to have locally?
