Hi, I am having a problem importing a v14.c model file into v12. There is nothing new in the file (No SSS etc). It says "Invalid Model File [NAME]".
It has hooks and 5 pointers.

i heard that V.13 was a changing point for AM, so it is possible that stuff V13 and up won't load in versions earlier then v13. i dunno, I'm not an expert

AM is backwardly compatable - its just not forwardly compatable - ie as you have described it will often baulk at loading anything created or updated by a newer version of AM into an older version of AM. This is not unusual in the software industry.....

The file format changed in v13, so, it would take some modifying in a text editor to get a v13 or later model to open in v12...if it will work at all.

In v12, things were something like this:



In v13, it changed to something like this:



The change made the A:M file format more compatible with XML. Of course, there are a lot of other changes, so it might not be as simple as changing brackets and end names.

Hope that helps.

As it is often noted in the software industry, it is hard to predict the future.
Inevitably new features will not fit into current design constraints.
In most cases older files will open in v15 but uncompatible and obsolete feature settings may not be retained.

So, yes A:M is backward compatible.
Its forward compatibility will alway depend on variables not yet introduced into the system.
