No need to send any more profile, I think I know what's happening.
You are using profiles made with a fairly old version of the editor, one that saved "None" as the name of the jetway logo, if no logo was assigned. Recent versions of the editor don't do that anymore, but profiles made for it will cause the error ONLY with the new version, which introduced multi-liveries with P3D V5.
Before the update, it was just ignoring logos, and if that profile was used with P3D V4, it would have just failed silently to create a non-existing "None.DDS" texture, which showed no logo, which was in fact the expected result. Now, it's trying to find an object for an operator called "None", which doesn't exists, causing the error. I guess that profile wouldn't have worked in FSX or P3D3 either.
Yes, of course, we need to recognize this case to handle old .INI files to ignore that but, in the meantime, you should be able to fix it by doing as follows:
- Open the .INI file with a text editor.
- Do a Search & Replace and Search this string:
jetway_logo = None
and replace it with:
jetway_logo =
Save the file and it should be ok.
