I have tried to do some SEARCHing and came up with what I think my problem is. I posted this over on Rockies where I found a thread by Mac on Google Earth for a list of passes in CO. I asked him or anyone else for some help with my problem.
Hi Mac, hope you can open these links. I found a bbs for GE and some stuff on gpx files and the newer versions of GE beta won't read them. In the thread it says there is a problem with newer GE beta versions. Also a link to a site to download older versions which still allow you to view the gpx files. One guy says to go back to 4.0.2091. Since I'm computer illiterate I haven't tried it yet, so my disclaimer is...
Hopefully you or another computer genius will be able to shed some more light on the subject.
So hopefully this is helpful to someone else, if it works.
