I am trying to combine two databases (Agribalyse and Ecoinvent) so I can use some of the flows from Agribalyse that are missing in the Ecoinvent database. When I try to import one of the databases into the active one (from the zolca file), the screen freezes and the "finish" option doesn't react. I am trying to import the smallest dataset into the biggest one, but the other way doesn't work either.
