Sounds pretty far fetched to me. Integrate your Steam profile and prove it. Otherwise, you'll get no help here.
EDIT:
To clarify, if you don't prove that you own SRTT then your account will be banned. We will never help anyone with getting mods to work with a pirate version.
EDIT:
Actually this whole thing is absolutely ludicrous. The retail boxed version is Steamworks and comes with a Steam key so you don't even need the disk. Always count on a pirate to say anything to avoid spending a few bucks.
