What is the sample rate you are recording the USB mic signal at?

Be sure it is the same exact sample rate as the rest of the recording tracks.

If it's off... the USB different sample rate will drift out of sync.

You said it used to play back totally in sync..... have you accidentally dragged the track?

EDIT: one other thing.... is this in a MAC or windows machine? You said Mac but then talked about windows drivers.... I'm confused. I didn't think Mac used drivers from windows..... A windows computer can have serious problems if you are using 2 sound cards at the same time. This is often the issue with using a USB mic. It appears as a sound card, the computer also has a sound card or interface and they both have clocks that are not capable of being synced.... hence, as you play, the audio can drift from being synced since they are not synced to a common clock.
