copy and paste from one adf panel to another

Hi,

There might be an obvious answer to this question, but for some reason Smart design for data modelling ended up erasing my existing data model. So I saved the new data model under a new file name. So no I have two adf files with half a data model each. So I opened both adf files (2 tabs are visible in Aris Express now) but I seem to be unable to copy and paste content from one into the other. I tried right click copy and past, menu based copy and paste as well as ctrl-c and ctrl-v.

ANy suggestions on how I get both data models into one adf (exporting and importing as image is not an option as it needs to stay editable)?

Thank you in advance
