Map Downloaded but not Installed /Recgnised by Device and Basecamp

I just bought City Navigator maps for India online as a download version (not SD card). Then I went to myProducts account in Garmin and downloaded the map to my device (Nuvi 2455LMT). I also got the down load complete message in the window. However now when I look in the device, it does not show this map as an installed map. Then I again connected the device to computer to see if I can view the map in Basecamp. Even Basecamp does not recognize the downloaded map (along with UNL code).

When I open the device, I get no-detailed map found message. Why is the downloaded map not being recognized?


What is going wrong here?

Thanks
