I'm having difficulty installing Pirates from an old CD based version of the game. Cx recognizes it and starts installation from a crosstie. The installer starts and runs, but halfway through the install it asks to insert Disk 1, but Disk 1 is still in the drive. Is this a DRM problem? Is there a way past it without a crack? I thought that I would at least get all of the way through the installer without problems based on the info on the forum.
