8-9 came out with broken save system were as the one called Day 10-11 that includes day 8 and 9 is the fixed version and can take your week 1 save.
Yea, I'm not seeing that... My save files gave me an instant error that I had to "ignore", in order to continue. I had to get rid of most of the errors by saving it, one turn after loading the old save files. It sort-of worked, because the names were saved. However, I have no clue if it fully worked, because I am not sure what data it actually needed from the other game, or if that data changed anything in this version.
There wasn't much actual sex in 8-9 and 10-11. But, like the first week, there was TONS of dialogue and non-working functions still. (Map, the phone-system, useless stats that never get used, missing images)
Adding the lewd-patches gives me more errors, and tells me there are missing images. Then it directs me back to the "latest patch", which is the same patch I just added. (I am sure the two individual patches are messing with each-other. It said there were two duplicate files, one for the 8-9 and the other for the 10-11 days.)
I did manage to get one to work, then the other. I just had to install the first 8-9 patch, play those days. Then I had to save the game and reload it after the second patch 10-11 was added.
