I'm actually having the same problem I think ... ? I attached two screeshots below 'cause I noticed that the bin files look different from yours. Do you think this might cause the error?
I would say your files are corrupted due to an error downloading, because as you can see. my .bin files are quite larger (the icon is different only because I have UltraISO installed), so I recommend downloading them again.
Did your download with GOGDownloader or through your web browser? Because browser downloads tend to be corrupted not that rarely.
