I recently bought Toast 11 Titanium and every time I open it now it tells me there's an update. I click to download the update but then when it tries to load it tells me the signature is corrupted and improper? What does that mean, and why won't it let me update -- I paid for a full version of Toast 11 and I should get my money's worth. Anyone have this same problem and know of a solution? I tried contacting Roxio, but no response from them. Even paid the $9 for a support ticket but no reply in a week.
