I had to replace my xv6700 due to a charging issues (or lack thereof). I just went back to the link on my registration email and it let me input the key again. Make sure you get your run.gps folder from my docs moved over to keep your trainings and settings.
I have upgraded my ETEN M700 PocketPC from WM5 to WM6. Of course, the ID of the PocketPC has changed during this process and my old License number does not work anymore. I did not find any hint in the support section about what to do in that case. How do I get a new license number? Is it possible to link the License number to the owner name of the PPC so that you would not have to ask for a new license whenever you buy a new PPC or upgrade the OS?
