All - I need some help here. I have 5 different versions/downloads of Red Storm Rising (one of my favs) and not one of them is working past when I try to select a mission

I load Disk 1 fine, it has the splash screen, it shows the "4 new exciting games" screen, the year screen, the warship ID screen, the boat selection screen, the boat assignment screen, then the level screen, then the training/battle/or Red Storm Rising screen. After I select one of these (starting with just a training against a destroyer for example), it then shows the little story/summary. I them push my trigger and it asks for Disk 2, which I then hit F9, highlight disk 2 and hit F4 to select that disk (I have also gone into that disk's directory and highlighted the 1st prgm and hit F3 to select disk too), then after I hit the trigger to select, it either freezes there (annoying) or it goes to the sub's option screen where I can load the ship's torpedo stores but then when I highlight and click on call general quarters, it immediately turns red saying ENGAGING THE ENEMY and hangs forever.
Is anyone else having this issue? Again this is the same on any of the 5 versions I have of this game. please HELP!!
Thanks!
