moving audio tracks - pickup measure

  hey all, I've run into a problem with an Sonar project that I'm working. I've tracked an acoustic guitar with a click track. And I started playing (a string rake) before the countoff finished and the recording started. Result is that I now I have a nice acoustic guitar track and a drum loop track, where the guitar is slightly cut-off at the beginning b/c of my oversight. :) Is there anything I can do to doctor the track, or am I stuck. I might just have to move the drum track over one measure and start over, but I was wondering if there's an actual workaround. -ryan
