Adding New Ships To Star Trek Starship Creator

Hi all,

Recently I installed Star Trek Starship Creator on my Windows 10 PC. The game works fine, without having to use the Compatibility Wizard. However, when I select the Update option to extend the range of ships available in the game, the game cannot find any new ship data, even though I have 3 game disks: Star Trek Starship Creator Deluxe, Starship Creator Warp II and the Add-On Pack CD. Can anyone tell me what I'm doing wrong?

Thanks.
