Switch from NR70V zu NZ90

[Unregistered]

My german manual tells me that i have to use a new user name for the new device because using the old one would cause problems. So i did - but now all my programs i registered with my "old" name ask me to register again. This would get very expensive....Any hint how to switch to a NZ90 without loosing the "old" username ??
Or did i get something totally wrong?
Please help

If you are using more than one device on the same computer, you need to assign a different user name to each handheld. If you are replacing one handheld with another, you should use the same user name.
