-Iota-: Your saved games are stored somewhere else - in a special folder:
[Windows installation drive] \Users\ <Your username> \AppData\Roaming\Tropico 5\Save
Note - the AppData folder is NOT Application Data - it's a separate folder that's hidden by default. To see it, you'll need to switch on visibility for hidden folders.
Thanks, but I did find the location, it's just that there is no 'names' such as Tropico 5, just lots of numbers. Not knowing which one was the one I wanted, I copied them all to a USB drive and transferred them to the same directory on the laptop, but they don't show up - I just get the option of 'New Game' only; the 'Load Game' is greyed out :-(
