So I created another account on my computer that's not an administrator, so I had to install Blockland separately on that account. Oddly, when I boot it up, it still has all my old add-ons from my other account. It's still in demo mode though, so I find my old key and type it in.
It tells me that the Full Version is Unlocked for like three seconds before switching to Invalid Key and displaying the error spelled out in the subject at the bottom where you put the key in. I tried reentering the key, but this of course did not work. I got the exact same results every time. Since the administrator account on my PC will soon be locked where I won't be able to sign into it, this is a problem. Been playing this game since I was eleven and I still enjoy makin' stuff in it. I was hoping you guys could help me get this figured out?
