I am so scared to load 3.321 onto my vista laptop because of all the threads that say don't load it or you will loose your information. I have all my kma's on a backup hard drive. Is it finally safe to load Mtu onto my vista. I have 3.316 on it now and have not had any problems with it. Tell me if the upgrade is good for me and why. I don't know what features it has differently then 3.316.

Thank you
