I do not know why but every UGX .exe installers I download wont work. this pops up "Installer integrity check has failed. Common causes include incomplete download and damage media. Contact the installer's author to obtain a new copy. More information at: http://nsis.sf.net/NSIS_Error" I have tried going to the website and nothing has worked. I also have tried to extract files using 7-zip but i have no idea where to place the mod files.
