I have SW Composer 2018

The engineers here work with Inventor and I have been happily importing those files (iam, ipt) to use for illustrations in manuals and such.

Recently they did an update and now I am unable to open any files that have been updated with the new version of Inventor.

Is there or will there be an update to Composer to accommodate this issue?

Has anyone else come across this issue?

Can anyone help!?
