I bought ableton live lite 5.2 over a year ago and out of nowhere recently I have run into problems with it. everytime I try to record a track the sound is always skipping and crackling about every second or2. The more tracks I add the worse the skipping and crackling gets. A clerk at guitar center suggested I might not have enough RAM on my compueter, but the problem came out of nowhere without adding any more programs to my computer, and I even tried deleting stuff off of it to help but the problem continues.
