Hi Chazsi,
Just created an 8 bar verse, with 2 repetitions. 2 bar ending.{ (1-8). 2.} Did a Save As to desktop. Played perfectly. Added another 8 bars, now 20 bars long. Pressed play and got ONLY the first 8 repeated with 2 bar ending. Did another Save As, and pressed play. Got only the first 8 repeated with 2 bar ending, the additional measures did not play. Changed my ending measure from 8 to 18, did a Save As. Hit play and got the expected result, all 20 bars played. Did a "from" and all played. So, if you save as first, and change your measure parameters, you should not have a problem.
I did not mean to impugn your ability. I missed the obvious in your first post, "Do I have to do a save or something?" Yep, you do. Hope this helps.
