Hi Gramphos, I also had the same error as improvmonkey. I have Civ 3 Complete 'sold out' software edition, is that enough information regarding version number and patch? (I imagine they are the lastet of both). Basically it looks like the original .sav files, which are around 345kb on my PC, are being saved in the old 4.5mb plus format after using the savegame editor. Any ideas? I've used the editor before on older versions, fantastic. Thanks.
