Previous Version files not functioning

[Roo247]

I just opened a Dimensions file I created a month ago at most, and it removed all my elements, leaving me with just the plain box against a grid with no artwork material.

The material is visible in the properties section but not visible or able to be replaced or updated on the actual box.

Anyone else having these issues?

Are your file has been created in previous version of Dn?

Yes, My files were created no more than 2 months ago, just prior to this update.
