If you start up scar (with the default program begin end. setup) and try to run it and get an error, then your scar is not installed correctly and I recomend you uninstall it and delete the scar folder in program files (if using Windows XP) then install it from scratch (also, scar version 3.14 is the most used atm). After that, try running a basic script (just program new; begin end.). If it compiles and executes successfully, then update to rev 14 (which should be easy enough if you have SVN installed correctly already) then move the plguins and you should be set to auto. If not, maybe try posting operating software, where you download your scar etc. - pretty much anything that could influence the program in anyway.
By reading this signature you agree that mixster is superior to you in each and every way except the bad ways but including the really bad ways.
