Using 0.75 arcsecond CDED data??

I've finally managed to get Terragear to compile on my Linux machine, and have been trying to generate some scenery based on the Canadian 0.75 arcsecond DTED data available (free) from www.geobase.ca . I've been running into some problems though. It seems to pass the Demchop stage, but I'm not sure if it does so correctly. I skipped the vmpa0 and airport data steps (I just want to see if my DTED data works), does skipping these steps prevent you from getting output? At any rate, here is the results of the fgfs-tools-client program:

Output directory is .
Working directory is .
Tile id is 1712603
Center longitude is -110.664
Center latitude is 33.3529
X distance is -1
Y distance is -1
Load directory: ./Dem-.75

Running master clipper
(-75.25,45.375) (-75,45.5) 


The end result of this is no file (tile) is created. One thing that's really odd is that it says that the Center longitude is -110.664 and latitude is 33.3529....but I'm building around -76.00 long and 45 lat. The other thing that seems odd is that X distance and Y distance are listed as -1. Additionally, col_step and row_step are listed as 0. Is this a problem with the 0.75 arcsecond format (truncation to int perhaps)?

Thanks for any and all help!

Cheers,

Kris
