I like Titan Backup a lot and version 2.0 even more. I had the previous version and I have installed the new one on top of it without changing the registration key.
So far it is working great, but I would hate to lose its use because of some misunderstanding. According to what I gather from the comments section it seems that I have to be careful about choosing Registration keys for version 2.0.
I think the following scenarios will allow me to keep using this great backup program which I thank NeoByte and GAOTD to let us have it for free.
1) Uninstall everything and start from scratch and use the new key.
2) Leave the installation alone and reboot the computer before the day ends so that I can use the new key.
3) Keep the old registration key on version 2.0 and avoid rebooting until the day is over.
I would like to see if somebody can check it and see if I am mistaken.
TIA,
