Hiya,
Make sure you\'re downloading the file that is meant for your operating system. So if you\'re on Windows, make sure you\'re clicking on the download under the Windows section and not the Mac or Linux binary, and etc. If you\'re on a Mac, you should be downloading the .dmg, and if you\'re on Windows, ensure that your downloaded file is named \"PlaneShift_CBV0.3.012.exe\".
