Try to reinstall Blockland.If not, someone stole your key/you gave the key to someone.
i checked the key thing with badspotit wasnt stolen/usedsame ip for the last 7 monthsreinstalling seems a little much.i have a custom dir for blockland, could that have to do with it?
that's probably the problem, you probably need to reinstall Blockland.Install it in THIS directory:C:/if it's anywhere else it might do that
I've had installations on different drives, different directories, etc. and this never happened.I think this is a common issue, however I don't remember the solution. Make sure key.dat isn't read-only. You may also want to search if you haven't already.
