Needing help! Ok i had the MXSON Lomel Qualifying track on my MXS, but I deleted it to get the updated one, but I extracted the new file into the programs file, Then I startup MXS and it still has the qualifying one, and not the new one, knowing that I deleted it! HELP!

Whenever I delete something from my MXSimulator folder to get rid of something, it doesn't work! IT deletes the file, but it doesn't delete it from when I'm in the game? Please Help
