Synology Surveillance Station 6 License Crack
I bought a Synology DS218J to act as a surveillance server. 
It wasn't until I got the NAS and read the instructions that I learned that it only allows you to install two surveillance cameras in their Surveillance Station software for free and then you have to purchase a One, Four, or Eight pack of camera licenses to add more cameras.
Synology Surveillance Station License
While I understand v8 of Surveillance Station is in beta, I didn't expect it to invalidate one if my licenses. I have the built in 2 camera licenses and I purchased 2 additional 4pack (CPL4) licenses. Right after I upgraded Surveillance Station decided to mark one of my licenses as INVALID. It then prompted me to either add more licenses or remove cameras. I have a total of 9 cameras with 10 licenses. In theory even if one of my CPL4 licenses are marked as invalid that would leave me with 6 active licenses, but Surveillance Station knocked all cameras off and deactivated them.
