random suggestion, because I recall vaguely some incident I had in the past... and I then had to create a dummy library just to get things working in some import/export procedure:
1) Create a new empty library in any location, name it
Templib, for instance;
2) Switch to that empty new library;
3) Run the import tool from within that empty library "Templib", I mean, whilst that new empty library is active, proceed to picking the same paths as you did before
somehow that worked for me back then
