Zoom in the tracks to align them. If they are slightly off, click on the Waveform tab on the top and make an edit (likely deleting or adding milliseconds of blank space so the tracks align). Click the Multitrack tab at the top to return to the original screen and check the alignment. This is kind of a trial and error, might need a few tries.
Do this every few minutes to insure things stay aligned. Make adjustments as necessary.
Make any other edits you want.
When you finish, go to Multitrack > Mixdown Session to New file > Entire Session
When your mixed down file is ready, File > Save As

Thanks a lot Will definitely give this a try sometime soon.
