Oregon 550T missing waypoints - Help please

This seems like an Oregon problem. These devices, especially the newer Oregons have a lot of bugs in reading and writing correct gpx files. Attach your gpx file here and someone should be able to take a look at it and figure out what is tripping up the Oregon.

So far I have discovered that there was a missing Current.GPX file in the Current folder. I don't know what phantom made that disappear.

From Basecamp, I've learned that I can select a waypoint, then make any change to it's properties, and exit. The changed waypoint now will appear on the Oregon device. I wish there were a more global way to resurrect all of the missing waypoints that are still correctly showing in Basecamp from my device, but I haven't stumbled on any way, yet.

Using my previously learned way to restore a single waypoint, I selected all waypoints in the properties window of Basecamp and globally changed the Icons, then exited. Now I have all my waypoints back in the device again. That's a pretty extreme way to do it, but it worked. No doubt someone will figure an even better way, but the whole problem really sucks.

I discovered the missing waypoints when out kayaking yesterday, which, of course, was when I needed them. Other than putting fresh batteries in the device, which was powered off beforehand, I have no explanation why this loss of critical data occured.

These Oregon devices are notorious for their non-acceptance of correct gpx files. In this case though, the culprit is the missing current.gpx. Can't imagine what you had in your data to make the device unhappy.
