Support and Software Assurance (SSA) appears to be well worth money considering you get access to all the online library content (both newly added and existing libraries), ability to download and upgrade to the newest version of Chief Architect at no extra cost and priority technical support. If your SSA runs out and you don't renew it, you will not get access to the things I just mentioned. SSA also allows you to get a discount if you join any of CA's pay-to-attend online training webinar's.
