Upgrade from RW5 to RW 6 contents do not show up

i updated RW to version 6 today. followed all the tutorial with opening the resent version , update to latest Version5… and safed it.
opened the Project in new RW 6 and at least everything showed up , frame, colour, font etc, but not a single content of the contents on this my projects.

what is wrong


Have you tried first, without saving with the newest RW 5.4.1, to convert the RW 5 file?
Perhaps, you must search the “old” new RW 6 file and delete it.

Then you can re-convert your RW 5 file (Important, save the RW 5 file with RW 5.4.1).
Have you read this thread?
