support is better than on any main stream company, have you asked for support there?
if you have proof of purchase then contact support, they will deal with you and it will work, game works 99.9% on pc's with no issues, the .1 % is a known problem for the odd users who have broken codec's which has been explained to many or most anyway, if you have ever installed any codec packs or files etc, it may have damaged a odd codec file that the game needs and then to check if it is this, just renaming a sound file points it out 99.9% of the time, if it is it and not something else, then a simple codec repair tool fixes the problem and it's sorted for many.
to get key to work on steam if you bought it from matrix is contact them, they will sort it
We are also going to offer a free Steam key to anyone who bought a copy from the Matrix Games or Slitherine store, once the game is available on this digital platform!
so good luck, and contact support, as mods will see this, but it's you who will need to contact them, as if they don't know the problem, they can't help fix it
