Paste error when loading Hierarchy Board

Hello,

i get the following error when i try to load a saved Hierarchy Board:

When i hit OK only blocks are loaded with no wiring between them. If i try to rewire the board and save it (with a different file name) i get the same paste error and no wires when board is loaded.

This apparently happened after i accidentally saved a blank project over a project i was working on. The Hierarchy Board was part of the project i was working with but was already saved as a .dspbrd file and was not even sharing the main folder with the project.

I attach the corrupted hierarchy board. If you could please check if you get the same error when loading.

Thank you

Omar
