Hey fixed it.
Could have been to do with me changing from Windows xp media edition to Windows xp pro.
Think the file etentions were on some diffrent setting.
Had to copy the origional config file then edit it to make it my new one. Then change its name to autoexec without the .cfg on the end as it was already a copy of the origional file - which was a cfg file.
Bang it works
