I can open the project but i open for example the interior tab and select furniture and do not see any of the custom furnitures that i had imported in the previuos version, but if i go to the folder the imported .3dn file is there. That happens with all the imported objects no matter if is furniture or any other or texture.
If i try to import again gives me a message that the file is already there and that i have to use a different name for the original file i want to import
