Fahd, I had the same issue -- that "Find" line you identified is the wordletized version of the line in the instructions. Just add the hack's new line in the instructions after the one you identified above and it'll work (the new one will just not be wordletized, but who cares).
There are a couple other spots where new wordletized changes require you to identify the equivalent of the old non-wordletized version (e.g., in the user search and the search results) -- but the "add after" or the "replace" code all works if you can find the spot to add it (which is not that difficult). Just have backups before experimenting!
