Don't know if this latest update has fixed anything, but on my Win11 Pro computer everything works fine. Other than running in Compatability Mode (if you keep having problems), sorry but I can;t suggest anything else to try.
How much of the stuff is with NTR of mom vs the stuff with mom in Non-NTR? I'm fan of non-ntr mom-shota and not into optional NTR games where NTR get much kinky and hardcore than non ntr route.
Most of them have been nuked. You can probably still find some copies from places like SVS, but I'll warn you, the game was never finished and there isn't a whole lot of content.
