My savings of v102.2 : "C:\Users\XXX\Documents\Simutrans"
BUT how come my saving of v102.2.2 : "C:\Windows\System32\config\systemprofile\Documents\Simutrans"
???
Here I am worried about my abilities and knowledge will be (extremely) short in this case - but I am going to try to help you. I don't comprehend how dir C:\Windows\System32\config\systemprofile\Documents\Simutrans could be created.
Download FreeCommander (http://www.freecommander.com/fc_downl_en.htm) and use it with options Show hidden files and Show system files. Then you should can go into dir C:\Windows\System32\config\systemprofile\Documents\Simutrans - and simply copy all saves from this dir into the first called one (C:\Users\XXX\Documents\Simutrans).
I know it is very stupid and simple solution - but: when it is stupid and simple, then it should work best. ;D
