Game loads, however music sounds echoed and cannot choose any options

Pretty much as per title. I loved this game last year but not had a chance to play until now. 9.1.1 - perfect ime to return I thought.
Anyway...

I start the game and get the screen size option - use keyboard to select screen size, all good.
The title animation runs and then I am on the main start menu - the music sounds somehow speeded up, it returns to normal when I press Esc (but then I can only quit or return!).
I also cannot navigate the menu at all - keyboard or joypad.

Specs:
Windows 10 Home
GTX 970 6gb DDR5
i7 6700HQ
8GB DDR4 RAM

I have tried using Compatibility - setting to Windows 7 (which it worked on before) and Admin.

Searched all through here and couldn't see anyone with a similar issue...

I had something similar
you need the launcher in the folder it came with, it seems to not work when taken out
If that doesn't fix it, I don't have anything else

Do you have dedicated arrow keys? Did you remove the .exe from the folder with the game's data files?
