Red map on Active Sky Next?

[r0drig0 1]

Hello,

 

I bought Active Sky Next last week and I am absolutely happy with, but today happens something weird with the map. The map becomes red like this  link to image http://s76.photobucket.com/user/rgflores/media/fsscr279.png.html

In this way it becomes difficult to read. Any idea to fix it?

Thank you!
