i'm working on a freshly formatted machine so i've yet to install my AVsoftware but it's seems that i need to do that as soon as i wake up. i thank you all for the re-affirmation of not to try it. i'm way skeptical when it comes to anything that doesn't have the default extensions on it, so that is why i asked. and i'm sorry about this becoming off topic. i do understand that it has derailed the course. having said that, i wished i'd have known that when i made the purchase, it seemed like there were people who loved all of the above carts. r4i was the one in stock that could get here in time. what a shame. again thanks for the heads up.
