Launcher problem

Hello.
Next to the base game, I have the following EPs/SPs installed:
-Ambitions
-Late Night
-Pets
-Seasons
-University Life
-Master Suite Stuff
-Diesel Stuff
Today, I've downloaded Island Paradise and in order to install it, I've tried updating my game from 1.50 to 1.55. However, the Launcher wouldn't let me, so I used the SuperPatch to do so. After the update finished, I installed Island Paradise, cracked ALL my EPs and SPs with the ultimate fix for 1.55 and tried to start the launcher. But when it did start, I got an error message saying 'There was an error during startup. Please see the Log for more details.'
What can I do to fix this problem?
EDIT: I've tried deleting the Documents/Electronic Arts/The Sims 3 folder, but the problem remains.

Hello,

I'm recommending to update your game once again with this manual patch again before trying to bypass the launcher. Please update your game and crack again. Then try to open the game and let me know the result.

Updated using manual patch, worked. Applied fix again, worked. Played for a bit. Downloaded The Sims 3 Supernatural. Installed. Cracked. I open the launcher and it says my base game is at v0.0.0.0 and my base isn't even shown up in the area where your installed EPs/SPs show up. Hlep with this one? Island Paradise, Late Night, Seasons, University Life, Ambitions and Supernatural itself don't show up either.

The problem is that you put the crack of supernatural instead of the fix crack of patch 1.55. I guess. So put the fix crack of 1.55 in the C:\Program Files\Electronic Arts\The Sims 3\Game\Bin
And the game should work again.
