It's a test version, someone has already posted on previous pages, that BON has fixed that bug and patreons can reupload the 1.8. The only way to avoid this bug is to start a new game in 1.7 and get the key there, save and put this save into 1.8, or if you have fully completed quests in 1.7, you can use that one and do laura's and amy's quests. However there's few scenes that doesn't work in test version (deepthroat scene with laura in the bathroom at 11am o'clock, amy's titjob scene when you invite her to play (19-23 hr) and laura's scene on the beach at 12 am). Either use save files that were posted on previous pages either create your own in 1.7 version of the game and use it. The last option would be to just simply wait for fixed 1.8 version of the game. I hope, I helped you,buddy
Edit: For those who were stuck with laura's quest after you fixed her pc, you need to buy a car to advance her quest, not sure if someone has already mentioned it
