Launcher says "error during startup" and closes.

I'm honestly not sure if this is the right place to post this (I only made this account to make this post), but I need some help. I just downloaded Ambitions, followed the instructions and everything and came to an error pretty quickly. I try to start up the launcher and all I get is an error message that says, "Error during startup, check log for more details." I looked around a bit and found the thread for the issue, however, it didn't work. No expansion packs that I didn't have were there in regedit, and I tried to fix the values of those two mentioned files but that didn't fix it either. 

I still get the issue message and it's getting really stressful for me. I just want to be able to play the game, you know?

The place that I downloaded the Sims 3 and about 4 other expansion packs is C:\Program Files (x86)\Origin Games\The Sims 3. And I have 6 expansions downloaded in C:\Program Files (x86)\Origin Games\The Sims 3.

Is there something I'm doing wrong with the registry? Any help would be very appreciated.

EDIT: I also thought it might be important to add that in the Sims 3 file, there are 2 files that weren't in the screenshots of the thread. They're called "GameExplorer" and "GDFbinary". Not sure if this matters or not, but it never hurts to add.
