To set up network account between multiple computers and devices, you need to create a Notezilla.Net account. When you right click on Notezilla icon and choose 'Sync' option, you will be shown an option to "Create new Notezilla.Net account". Please click on this button to first create new Notezilla.Net account in order to sync Windows sticky notes with the cloud.
Your order details are not related to the Notezilla.Net account. This is the reason "Sign In" is not working. So you will have to create a new account first.
Make sure you create the account from the Notezilla that has all your important notes. Once you sync those notes, you can go to the other computer, right click on Notezilla icon, choose Sync and click on "Sign into existing account" and enter your account details to download all your notes.
Once you do this, both your computers will be in automatic sync every minute.
