Hi, have you tried uninstalling and reinstalling neo4j?

I installed neo4j at another computer and then I was able to load the file after adding this line to the configuration file neo4j.conf

dbms.allow_upgrade=true

since I had installed a newer version of neo4j than the one I did dump at.

However, I did never find out why I got the "Not a valid Neo4j arcive" but at the moment I do not need it to work.
