Can't update TS3 base game from 1.3.24 to 1.4.6

So, after searching Google and coming up with the same information, none of which is working, I've been faced with an issue with updating my game.

I've uninstalled and re-installed twice, the updated from the original to 1.2.7, then to 1.3.24, only to be met with the same error, that being the 'Invalid File Found' error when attempting to update my game from 1.3.24 to 1.4.6. Yes, it is a pirated version of the game, and like an idiot, I forgot to save the original versions of the .exe and the TSLhost.dll file to my computer before installing the first update.

According to The Sims 3 Patch Log Viewer, the TSLhost.dll file is the one that is invalid, and so I have a couple of questions. If I were to replace that, would I replace it with the same file from the original game, pre-updating? Or would I replace it with the file from 1.3.24? With that in mind, does anyone have a copy of the original file? I've been unable to find one online, and I'd prefer not to have to uninstall the game again as it's working perfectly, I just can't get past that step in updating.

Reinstall.
