I couldn't start the game for a couple of days (I used the newest version of the mod).

Then the creater of the mod, writes on Nexus that version 1.3.2.0 is not usable with the new patch, but that version 1.2.9.0 is.

So I installed the earlier version and now it works (although I must say it is very unstable).

If the new version works for you, then cool, it's doesn't for a lot of other people as you can see in the bug reports:
