Hi again,
it's possible your map is on the upper-left side of the track in TE (that's what it did to me).
In the left panel of TE clic on the [+] corresponding to your track and do the same with the last line (Misc Config). You should have something like this :
If the first two values (POSITION) are 0 just change them to something else (for example 100) so you could see where is your map. Obviously, you'll have to adjust these values to fit the positioning of the map on your track.
In the same way, your map could be too small to be seen. Change the third and fourth values of the Misc Config panel (SCALE) to higher values the same way than before.
Maybe the map is realy too small so you have to go back to your Photoshop/Gimp/Whatelse and make a bigger picture of it (at least 500 x 500 and better should be 800 x 800 or 1000 x 1000).
If this doesn't solve your problem, just tell in a step by step way what you did exactly from "converting to bmp" 'till "Could not create anything!!!!!!!!!!"
Cheers
