They're sending CDs with 1.17 on it now?
I suppose the standard thing to try is to delete and give the game another install try.

I'm not sure what would cause range check errors if you weren't modding the game yet.
It might be best to ask over at strategy first, if their forums are working yet, since they're the new official distributor and they'll have more experience with the latest CD.
