Guitar Tracks Pro and pc help

[Thrakk_Crimson]

i am running guitar tracks pro. i installed it, and it ran fine. i got a new computer, installed it and it ran fine. then one day, it turned on me. i can record on the first track just fine and it sounds as it should. but when i go to record on the second track, it seems to echo the first track extremely loud and distort it, and you cant even hear what i actually recorded on the second track. so all you hear is a really ugly distorted ear splitting version of what is on the first track. i know i am using a regular sound card and that isnt good, but it used to work fine. i plan on getting a new sound card, but what i had was good enough for the time being. i dont think it is guitar tracks pro though, because i downloaded a demo of another recording program (i forget which one, but one of the major ones) and it had the same problem. so i assume something in the settings of windows has been messed up, does anyone have any ideas?????

thank you for your help.
