Aye, don't forget to turn of autopatching
If you've got autopatching enabled (in Steam, for example), the current game version is 1.0.3, and the latest trainer available is for 1.0.2.
Not too many mini-patches for this one (not like TF2 or DotA2), and seeing the fixes, tweaks and additions they make... You don't really want to turn off auto-patching.

It's not that bad, Cal & Co works faster than game developers - quite a bit faster as well.
