I've been playing 7th guest on my Dell laptop. It's been absolutely fine up until the point when you should be going into the attic. We cannot go in that door. we've solved every puzzle but the hated microscope game and been through every room again. Still can't go in the door. I haven't been able to find the patches, unless the game is patched by running it in some ancient Beta DirectX version. I'm assuming this is a patch problem...if someone has the patch file or knows a working link I would love to hear about it.
