I recently bought a new sander and registered it online. In the process I noticed that my old login didn't work and I needed to create a new one which was no problem. However, none of my tools previously registered under my old login (which, by the way, used the same email address) were shown under my login. For most tools this isn't a problem since they are out of warranty already. I do own at least 3 that are still under warranty. Must I re-register those?
