I am trying to change my email address to the Kaspersky website for all applications. I really do not like Gmail! Ok to use on my cell, but not on pc. It allows me to enter new email address, but it says that my password is incorrect. I know that it is not. I only have one more option left before I get locked out. Does it want the Master Vault password that is used for Kaspersky password manager? If so, it doesn't say that.
