Hi! Both the SteamCMD server MM and both my own game MM doesnt work. When i press any kind of .rcmp to install it install it. But with a 0 KB .mft. Which means i cant use the mod. This issue is there with any content official or 3rd party. Thx Csaba.
Did you try it with running the Mod Manager as an Admin (Mouse Rightclick on it and select "run as an Administrator")?
