Slitherine

I just tried to update my game - which I bought from Matrix games - and got the message that my serial number is not correct.
any ideas??

hrm. As i understand it, the patches from slitherine and matrix are different - you need to get the matrix patch for your version or it won't work.

If i recall correctly, the matrix patch is obtained by clicking the check for updates link on the launcher you get when you start the game. Just to confirm - current version is 1.8.
