Hi. I am having similar problems as those players experienced in the last few pages. I started with v0-10, and then played both v0-11 and v0-12, neither of which I had any problems playing old saves. I had previously played with Incest Patch and (I think) Scrappy's Walkthrough/Gallery Mod.
I had tried loading v0-13 game having loaded updated Incest Patch and I think it was Scrappy's Walkthrough/Gallery Mod. That did nt work as got error message and when I clicked ignore, it took me back all the way to the start of the game, asking for name to be input as others have mentioned. So I deleted that version, went back to the initial zipped download file and reinstalled it from scratch, and again got error message and when I clicked ignore, it took me back all the way to the start of the game, asking for name to be input.
I know there is not a problem with my v0-12 saves, because when I load up my v0-12 game (I ALWAYS keep previous version of game until I know new version has correctly loaded), it still loads and plays those v0-12 saves correctly within the v0-12 game.
How can I check, in my v0-12 game, which Incest Patch and which Gallery Mod I had??
Presumably that would help narrow down the problem and clarify which Patch / Gallery Mod I need to install for v0-13?
