Hey, I tried eveyrthing in the video and the instructions given but I still can't play episode 2. It say's "Episode unavailable". I have steam running in the background, everything. 
Viewing post in Haunted Memories Inkl. Episode 2 Welcome home comments
Have you really applied everything correctly???
I assume you didn´t apply the Episode 2 patch correctly.
And one more Thing: instead of wasting my Time only showing the bare Minimum show me a Screenshot of your Gamefolder, your Screenshot does not help at all.
I don´t mean to be inpolite.
It is just a Fact when Troubleshooting a Problem on PC you need to show everything even without asking, otherwise I can´t help you.
I have now uploaded a Windows only Version with everything applied already. Just download both Files Haunted Memories (Ep2 included Windows only).7z.001 and Haunted Memories (Ep2 included Windows only).7z.002, unpack them and launch the exe.
If this works this just means you didn´t follow my Instructions correctly. Than Have Fun playing Episode 2 now...
If this didn´t work than we have another Case on why Gaming on a Laptop sucks because this is most likely another Compabiltiy Issue.
