Neighborhood Download Problems = Corrupt Files

After downloading Barnacle Bay and others, I go and extract them. When I do Winrar states that they are corrupt files. I have re-downloaded them all plenty of times. Any idea why it keeps saying this?

Are you downloading the Neighborhoods from the Mediafire Provided from here. I'd link it but I can't seem to locate it and I cleared my history today. I found it. I didn't notice this in any of the sticky threads, hint hint, or I just missed it. But there are a lot of topics with bad media fire links floating around here. Anyway if you're not getting the files from here---->"error new member" (LOL) should. Make there here ---->https://games4theworld.forumotion.com/t1224-how-to-download-riverview-for-the-sims-3-fix-closed?highlight=riverview since I can't post external links yet The media fire link is in the first post and that is where I just got all my neighborhoods from within the past 24 hours.
