The problem is licensing. I have a 3 channel corporate license for...TV 8... So, what they do is try and get you to upgrade to a higher version.... ESPECIALLY sneaky is the window that pops up "There is a newer version etc etc" and prompt you to install it.
I tried this once and received the message "your license does not support this version". The client now has a setting where you can tell it not to notify you of updates unless within the major version of your license. I believe so many people got screwed by updating and then having a non functional license that they HAD to add this.
IIRC my corporate license was somewhere between $3000.00 and $5000,00 CAD dollars and they wanted over half that again to enable my license for version 11.
