Thanks for your prompt reply, however I don't know where to find the config.bat file. It does not exist in the Mac version, and if I download the Windows version, there is only a single file named blockland.exe. If it is some kind of self extracting archive, that contains the batch file, of course I cannot run it. Where else can I find the bat file, or could you post the actual command and switches as a reply here?
Thanks again
