At least one original filter used for graphics imported by reference is not available
We have files made with FM11. We started to use FM2020 and some files give message "At least one original filter used for graphics imported by reference is not available, or the imported file's format has changed. An alternative filter may be used if the file is recognized as a graphic FrameMaker can import." when opening. When you scroll the file at some point FM2020 crashes. Any ideas what to do with those files?
