In case you can't get this mod to work, it's cause is usually other mods or old mods interfering.
So clean them up, and also disable prison loading when the game is started:


Start PA

Click on "Open Save Folder" in Options and quit the game.

In the explorer window which got opened by the game, remove or rename the folder called "mods", this will clean up all old incompatible stuff. The game will recreate this folder if it doesn't exist. It's probably best to unsubscribe from other mods here in the workshop as well, so they won't be downloaded again when you start the game. Make sure you've only subscribed to the CombiPack and nothing else for now.

Edit the file preferences.txt with Notepad or Notepad++ and make these changes:

V2Gui true
ShowAttractScreen false


Save, start the game, let the CombiPack download. Quit the game when it finished downloading.
You can also download this mod outside of Steam, simply follow my Guide to install mods manually.

Edit the preferences.txt again and set:

Mods "Murgh CombiPack for PA 18"

including the quotes because the name of the mod has spaces.

Save, start the game, give it some time to initialize all the stuff since this mod is HUGE.

Keep an eye on the debug.txt if you have problems, perhaps it can reveal a cause.
If your machine can't handle it, perhaps some other program is making this happen. Disable things like Discord overlay, the Windows 10 Game Bar, it might help.

Changing graphics drivers may also work. I'm running this thing on Intel HD 4400 with no problem. Nvidia/AMD cards seem to give more trouble than a simple onboard gpu on some systems. Perhaps your system may be one of them. AMD cards had some resident software as well which causes PA to crash.

A fast SSD instead of loading this game from a harddisk, and a minimum of 8GB ram is recommended. If you have only 4GB or less then the available memory might be eaten up very quickly, resulting in the game accessing the windows swapfile. This will severely decrease the pleasure of playing this game due to constant lag spikes.
