I'm looking for some guidance on how to correct the Resource not Found error message when opening a title. Sometimes I get this, sometimes I don't, depending on how I open a file. Thanks in advance.
That looks like a Lectora Desktop / Publisher or Inspire issue. I guess with everything called Lectora it's a bit confusing, this is the forum for Lectora Online. You should email support@trivantis.com and have them look at your title.
