OK, I went to the specified web address (which I had previously visited) and I filled in the blanks (again) and sent it off. I got the same computer-generated response, urging me to upgrade to version 4.0.2, and sent to my old address. Fortunately, I can still receive mail at that address, but it's about to disappear--and I still haven't discovered a way to notify LimeWire of my NEW address. Yes, I have pro version and had just upgraded to 4.0.2 when this problem came up. Again, how can I let LimeWire know my new address, so I can be notified when it is time to register again? I did show it on the form I filled out, twice, but apparently it has not been recorded. Help!
