The Advanced Geocaching Tool got an update (0.5.2). For the original announcement, click here.

Just to clarify, downloading geocaches is possible without a premium membership at geocaching.com. However, a bug prevented downloading of geocaches with negative latitude or longitude.

Updates include:
* Fixed downloading of geocaches.
* Adaptions to new geocaching.com layout (downloading hints works again).
* Fixes in the 'calc'-feature.
* You can now type a waypoint in the 'notes' tab and it will be listed in the waypoints
* You can select a waypoint and have it shown on the map (great for solved mystery caches)

Again, please report any bugs at the bugtracker. This way, I will get an e-mail notification and be able to fix your bug faster. I just occasionally check this thread.
