Custom Content not installing properly[Solved]

First, I'm sorry if this is the wrong category, but it's not YOUR downloads I'm having an issue with, it's ones from all over the internet. :newfag:
Basically, I put all of my ".sims3pack" files into C:\Users\Krissy\Documents\Electronic Arts\The Sims 3\Downloads , went into the Launcher, to Downloads, selected all, then clicked Install.. It said Installation Successful for all of them, but when I open the game, they aren't there. Poof! When I go back into the launcher, it no longer says any of them are installed. What's going on? I have all of the latest downloads from you guys, version is 1.42.130.019002..

This is only happening for the CC I installed today. All of the CC/Store Content from you guys seems to be working well enough. The main place I got my files from is: http://www.thesimsresource.com If anyone can help it would be GREATLY appreciated. >_<

The game itself runs fine, no lag, etc. All of the other items are there, just none of the CC I installed today (Which was a lot)

Does it help if you install only a few at a time? If it doesn't, you may have to try this.

Eheheheh.. Darn. It seems that installing about 4 at a time works. I guess I was just overwhelming the poor thing, lol. Thanks, Lady ElDi Goodness, this is going to take forever..
If it's okay with you, I have one more question while I'm here -- Sometimes, it says "This package is already installed," but I'm pretty sure it's not.. Is there a reason behind this? Example:
