for the 4th box in your brr settings link it to your BVE.
in BRR, try using Process Only instead of Start BVE - the brrtemp.csv file should be in your C:\Program Files\BVE\Railway\Route folder
Since you're using windows 7, make sure BRR has permission to write in that folder. if you are not sure, instead of double clicking the brr icon directly, right click on it and pick Run As Administrator. (if you are an administrator; if not then i cant help you lol)
