Yes you are correct, Thats why they blacklist keys almost every month and or every release. But by what i read even though they do this it looks like it is'nt working well for them.

From what I know it works just fine, people are not getting their keys renewed, some may if they can provide Slysoft proof of original purchase.

Thats great, As long as my upgrades work thats all i care about. I could get into a deeper conversation about this but im not going to get into a how to on disassembling someones software as this is a CD/DVD fourm and not a underground programming site and or fourm. In the software world almost nothing is safe trust me. Hardware locks will even stop only to a point which this software would never use because of costs. Anyway if you know what MicroStation is there 10G programs and they can't keep ppl from getting it. Some ppl have very good programming skills. Anyway as long as mine is up to date is my only concern.

You are correct, that should be your only concern.
