My experience with Serif's purchased programs ... long story short ... "no more"!
1. The toll-free numbers are not toll-free. I had phone bills for every activation call made. And yes they do take time to put you on hold and then to advertize products targeted to your interests. Contrary to the pop-up activation screen; no the calls are not fast.
2. After doing a reinstallation of the OS; none of their purchased products could simply be reinstalled like everybody else's. I think you have to make all those phone calls again to get new numbers for each and every Serif product. I sent them an email expressing my displeasure at their activation practices.
3. They did not send me any spam ... you could request deletion from their mailing list if you didn't want to read about each week's special offers.
