I still have 8.5, it's the last version I purchased. Just couldn't get into the redesign of X1 and beyond. I'm wondering, if I have to reinstall, will it authorize via serial number? It does now, so hopefully it will after the servers are down. Of course, I have a system image, so that would save me. In fact, as has been pointed out, it should save anyone with any version. Everyone should make an up to date image asap!
