If the last two updates are any indication, the dev's have intentionally added game breaking code that attacked so far cheat mods and now unofficial versions. You can expect more in future updates. I would suggest deleting your game file and saves (which there are instructions on the first page for how to find them) and downloading the full game unmodified. Its 2.09gigs but well worth it.i am using compressed version and applied inc patch.
In the future you will only need to delete your old game and download the new one. Since saves are in a different file, they will still be there. NLT is doing a good job managing file size.
