Re TOPO Sweden.
I installed one (of 5 sets) set and indeed get the TOPO maps in Mapsource, although they look different from displayed on the swedish garmin website.
No green forests etc., only elevation lines etc.
I have the five files but can only register one at the same time. When I register a next one it replaces the link in the register (checked) and I do not see a difference in Mapsource.

Regards,

Hans
