The Sims 2 Downloading Files Problem?

I go to "Mod the Sims 2" site all the time and never had problems until now. This problem could also be that I don't have the Sims 2 on my computer yet because I'm waiting on another Sims 2 game to come in before I load it. I would go on the site, sign myself in, and click on something that I want. I go to download and I get this icon (no matter what item it is) next to the download link that looks like a floppy disk with a smiley face on it. Now once it's downloaded it comes up in my Winrar. So I click any of the item and I get another pop up that says "Do you want to connect to the internet, or a browse" and it gives me options, but I know that something wasn't right. Now the icon next the item once I download is a paper with the icon windows on it. Can someone help me on what is going on? I went to the sites help and it didn't describe my problem. Please don't send me the link to "How To Download File" off that site, I already went there.
