No it doesn't show me as trial day remaining. It shows me "Deactivate license" button. I certainly didn't install any cracked or pirated version, but I just don't remember buying Start10, only Start8.
@The_Gear, my account is different from the one I use for the forums. I had forgotten the password so I made a different account and then I retrieved the password.
Anyway, thanks for the replies. I will look my other email accounts to see if it has the Start10 key.
