Hi,
If you recorded each album side as a separate file, you can just drag the sides around in the list of recorded files in the Split Tracks window. Then (because bug, which we will fix), right-click in the waveform display (or Ctrl+click, on the Mac) and select 'Regenerate waveform display' to put the waveform display right.
If you recorded everything as one big file then VinylStudio can't help you with this I'm afraid. Your best bet would be to edit the file in Audacity, then resume working on it in VinylStudio.
