hi heres some torubleshooting tips.
1: make sure you are using the right region that has the .hgt files. i assume its region 1 since my seattle route is near bye.
2: next make sure your routes latitude longitude values are correct, if you are missing a "-" sign in front of the longitude coordinate when you first assigned the value to your routes starting location I garuntee it wont work!. should be -109 decimals to -116 decimals roughly for your region. your lat should be 45-48 decimals. download those coordinates from the strm data website anything that has those numbers in it from your region you should download. use the map guide on their site to help with the right region.
3. when you first gave your coordinates to set up your route make sure you put the right numbers in the right spot...i.e. lat=lat; long =long otherwise your mixed up.
4. make sure your SRTM DATA goes in the right folder. folder structure with your file: DEM\SRTM\xxx.hgt
theproblem is most likely human error on your part, doing the ".hgt mthod is really the easiest method. and works if you do it right.
