Horses and Sims Cannot Change Clothes/Saddle![SOLVED]

I played my game the day before and it all worked great! Today I started it, without installing any new content (only added two new horses but they don't make a difference) and my Sims and horses can no longer change clothes/outfites! Not even via the Master Controller Basic --> Outfit option (when I select this simply nothing happens)!

I reset the lot three or four times, re-started the game and reset the town, but still no changes. They just stand there and do nothing for hours, while the "Change Clothes" option is active. And when I cancel the action the action stays crossed at the top and the Sims can't do anything else.

What might be causing this?

Thanks ahead!

Hello,

Try backing up and then completely removing this folder: Documents\Electronic Arts\The Sims 3\Mods

I backed up, and restarted the game once again just in case and the problem got fixed, thank you!
