I've used CA for nearly 20 years. I started with Version 9 I believe. I do not like doing business with a gun to my head. This is what this feels like. Pay whatever we decide to charge for SSA or start over with a subscription service. Miss the deadline by a few days. you are outta luck. I collaborate with other builders/architects so I do not have the option not to keep current. We all have to have the same version.
At nearly 50 years old, I had no intention of switching to another software. I always figured that I would use it until I retire. I am not as sure of that now. I like the software, but there are lots of good options available. Doing business this way leaves a bad taste in my mouth.
