Hello guys,

This morning, my laptop which is working with windows 8 beta reminded me that I have to update my kaspersky antivirus software. So I clicked upgrade now. While during the upgrading, an error message popped up indicating that Failure: (Incorrect Username and Password). But I'm not clear about the username and password cause it was installed by my brother long time ago. And the last updating before this was without this problem.

Can you give me some suggestions?

Thanks for help!
