Welcome to SubSim Alastarohan!
First of all, let us know what version of Windows you have? (ie: Windows 7, Windows 10...) What version of Silent Hunter 4 do you have? (ie: v1.4 or v1.5...) Was your Silent Hunter a download or a disk version? (ie: Steam, Amazon, etc.). Last but sometimes the most important, where did you install the game to? (ie: default is "C:\ Program Files (x86) \ Ubisoft", or elsewhere??)
Did the game ever work after you installed it? It "sounds" like you can get to the menu, but no further??...
