Importing routes to Basecamp

Yesterday I posted about importing .gpx routes from a website. I was able to figure it out, and was able to import 4 of 5 routes into Basecamp (from the hard drive after unzippng) which show up nicely on my Nevada state map. However, I am unable to import the fifth route; I transfer I get on my computer, but when I go to import it the Import option is not highlighted. I have deleted and re-uploaded several times but seem to be stuck. Any suggestions appreciated.
