Also had a problem with GE5 and KML file. Showed only yellow push pins. Deleated old KML file and down loaded a new one. Ran it and all works fine. All the regular cache icons are back.
Went out at about 8am -4 temp. and a small wind. Did the walk and the look around, found the cache. Was I the FTF? No. The cache was found two days before it was posted. Got burned on that one. But I did find it.
