Blockland could not write the Key.dat file

[loliswicked]

whenever I go on blockland an error message pops up and says something like Blockland could not write the Key.dat file. I am running blockland from applications  but it still displays this message and only the default add-ons work and saving doesn't work.
Help please

Are you running Windows Vista?

Maybe you should try re-installing Blockland?

Make sure the Key.dat is not "Reading only"
