Don't recall the previous version I was using, it was about 3 or 4 years old. I didn't know anything newer was available because when I would select Check for updates, it would say "You're up to date." Anyhow, after updating to 6.4.3, most of the adventures, activities, tracks, etc. seem to be gone. Did the folder where these were maintained change? Hard to imagine they would be deleted by the upgrade or incompatible. Anybody have suggestions?
