Hello,
Record enable the tracks that you want to be playing (The record enable button is on the each track) for example your drum track, rythm guitar track and the guitar track you want to play on. When you are ready to play along with these tracks just
click on the play button above to start the tracks playing so you can play along on your guitar track without recording. Do not click on the record button above where the play button is until you are ready to record. Check the track you recorded the guitar backup track on to see what input it is set on (1 or 2). If there is a way to turn them off since the track is recorded. I don't know if it is conflicting with the input setting on the guitar track you want to play on. Usually your guitar should be plugged in to the 2nd input on your Fastrack and input setting in pro tools is 1 for your guitar track.
Hope this helps,
