Issue Opening .idml and .indd Files

[PoisonIvy]

Hey all. I'm new to Scribus, sorry if this is a dumb question.

Long story short, I'm trying to open a specific .idml or .indd file (they should be identical, just different file formats. I only need one or the other), but Scribus keeps saying that it isn't a supported format. I've been told (and seen several forum posts confirming) that Scribus is capable, at least, of opening the .idml file, so I'm not sure what I'm doing wrong.

Specifically, my error is:

File FILEPATH/FILENAME.idml is not in an acceptable format. The file may be damaged or may have been produced in a later version of Scribus.



The files are official Mongoose Publishing templates, so I find it unlikely that both of them were damaged. Any idea what I'm doing wrong here? Any help would be appreciated.

Solved. I needed to be using version 1.5+. I was using 1.4.8.
