Sims 3 EP errors. [SOLVED]

I already did that manual patch/fix thing that's printed in screaming print everywhere.
When I dl'ed Supernatural, it fixed all problems and everything was wonderful.
I have Pets on the legit CD and Supernatural on a download.
Everything was fine.
I decided, "I want Showtime, too."
So I downloaded that too. Went through install process.
Now it won't work. The game will not start up. Opening it from explorer does not work and running it with a right click doesn't work either.
What do.

Define "does not work" - there is no where near enough details to guess at what the issue is here. Does anything at all happen? Does your screen flash black for 1/10th of a second then go back to Windows? Do you get an error message? If you watch in Task Manager (ctrl-shift-escape) do you see the program at all?

The game does not open. The launcher opens, I click play, and nothing happens.
And no, task manager does not see it either.

Could you tell me the file size ad dates of these two files in your [Program Files\]The Sims 3\Game\Bin folder please? TS3W.exe and TSLHost.dll

TSLhost.dll - 5158 KB, 7/31/2012, 4:17 AM
TS3W- 13114 KB, 7/31/2012, 4:19 AM

Based on those files it would appear as if you need to re-do the Ultimate Fix. Whether or not it was done previously doesn't matter a whole lot, and it doesn't take a whole lot of time to do so you might as well just do it to ensure that it does or does not fix the issue. If it doesn't you can come back and call me whatever hideous name you like - I won't get mad, I promise.

WTF?!
I actually had already done that like three times and it didn't work.
I did it this time and it worked. >:/?
Well, either way, what's important is it's working now. Muchas gracias.

De nada
