[bstorey92]

Hi eveyone i have run into a predicament where i have deleted the nascar app using root uninstaller when i had my phone rooted. since then 2.2 froyo has come out and i want to put it on my phone but whenever i try to install it it says that the nascar file is missing. I have installed the app by saving it on a sd card but i still get the same error. any one know the answer? Samsung Epic
