No gmapsupp.img in Basecamp software

Hi,
After 1/2 year I want to use basecamp again to plan a route.
When I connect my Garmin Edge 800 to my PC and start Basecamp I only see the Worldmap and not the city navigator map wich was included when I bought the Garmin edge 800
Maps wich I have on my Garmin are:

* INTL Standard Basecamp, NR
* CN Europe NT 2014.30

I used to see both maps in Basecamp but now I don't see the City Navigator map anymore so I can't make any routes...
I renamed the file 'gmapsupp.img' in another name already, deleted it and put it back on SD card but nothing will work.
I installed basecamp on anoter computer and conencted my Garmin but still no card.
Can anybody tell me what can be the problem that I don't see the Card???

Thank you,

Gr. H. Lintermans
