Some game developers still use non free license archive types to compress their game distributions, so the app cannot open it. You have to manually download the game archive in web browser and extract with 3rd party program like 7zip.

Did some checking on the code side vs folder structure
in code img/Background/Background.png vs background.png
in code img/maps/Civilized Realms.png vs
Civilized Realms.PNG
Not sure if the list is complete for there are so many file links in code and it is getting late where I live.
btw I got the Linux fix version from the main mega link in the game download section for the mega link you provided did not work.
I fixed it for myself by renaming some image files, swapped the .PNG files into .png and the logo file into logo.png. The reason why no one has complained before is probably because people used windows or they fixed it or they just played it without most images like the map images.
The reason why it breaks on non windows systems is that browser one uses tries to open file called logo.png on the img/logo/ subfolder but there is only Logo.PNG there. Windows just ignores upper and lowercase and the browser finds the file. But on non windows system query for file called logo.png fails for that can be entirely different file.
On Linux etc you can have files like Logo.PNG, loGo.PnG and logo.png on same folder but windows just says that file with the name already exists.
Sorry for the long rant :P
