Are you using A7.06.1 trial? What kind of laptop do you have? A new one with Vista installed? Are you using Vista32bit or Vista64bit? Any other problems with games or applications on your machine? All hardware working and are your drivers up to date? Did you installed the service pack for Vista? A7 engine. etc.,? Always show the engine version number it helps ^^

Look if your script is using uppercase or not. Reason for your problem is because you are either using a space in the name and or wrote extremewarriors.wdl instead of ExtremeWarriors.wdl, if not then maybe some problem with Vista, but lets first try to change the option

So in the run options dialog change it to ExtremeWarriors.wdl -nx 30 Do not use any spaces in your file names.
