Aaarg! As i was installing X2, about a third way through "installing" and "extracting c:\Program Files\Cakewalk\Shared Surfaces\APRO.chm", i got the following catastrophic error - >>>>> c:\Program Files\Cakewalk\Shared Surfaces\APRO.chm An error occurred while trying to copy a file: The source file is corrupted. Click retry, Ignore, or Abort to cancel installation. >>>>> So i tried "retry" to no avail, so i clicked "cancel" Has this happened to anyone else? Will i need to re-download the setup1 through 4 again? Thanks, BTW - i have no control 'surfaces' or any other kind of 'surface' that i am aware of...
