That's usually the safest way, especially if you're not sure, where the problem lies.
Note for everybody having touble:
For the US version, you need ONLY the us-patch v1.0b
Only vor the Euro-versions, you need the euro-patches v1.0a and v1.0b
That's what I'm told at least, personally I only played the US-version since many years, always with only the v1.0b-patch.
Also make sure you don't use other mods that might be incompatible with this one.
