After the update, the game is coming up with these errors when I try to boot the game.

Anyone know a way of sorting this myself?

All mods have to be updated for 1.10 by the mod authors.

The 1.10 update seem to have changed many scripts and variables to adapt the interface and other things to the new expansion.. It will take an while before the mod makers have made the changes..

Indeed, i removed all the mods, and i had saved a copy of some file that i had to change for some mods, remplaced everything but it didnt work at first.
So i removed the attribut Read Only on everything under gog games directory, then i could launch the game.

I had the same issue, this solution worked for me. I'm running Win 7/64bit. Hope it helps you.

I reinstalled it and it worked fine, thanks for the replies though people :)
