The Geocaching.com website is having trouble just loading the webpages correctly, so that might be part of the problem. Another might be your browser. You need to be running IE6 or later, or you could also use Mozilla Firefox. I also have a Vist HCx and when I went on the site to download a cache to my GPSr, it downloaded with no problem, even though the webpages loaded extremely slow. Hopefully, the techies will finish doing whatever they're doing to the website, and things will get back to normal.
I called Garmin and they seem to think that it's not my problem but this websites server as I did receive an error msg. I don't have either IE6 or Mozilla Firefox. I am running off a 5 year old Windows XP machine that just got an upgrade to its memory as the hard drive was running real slow. Would that cause a problem because if I didn't get the memory, an IT specialist told me the machine might crash at any given time.
