Glad that you concur with me about activation. On four machines I am having the similar problems about activation. I bought TU, 18 months ago for two years with family license. Paid an arm and a leg. Within 6 months, no more updates will be allowed. After buying, 2 months later had the same "Catastrophic error" on all four machines, with both v5 and now with v6. Waste of money and time. Been working with support for the last two days, the last I heard this morning from them is following: So far, it has been wastage of emails for two days, and trying to install their debug TU.
