Error: Data error (cyclic (Redundancy Check)

Has anyone found  a way to fix this yet?  I bought a new computer and was installing all my sim expansions on it.  When i got to High end loft I put in the key and it started to install.  About 1/4th of the way throught the install it aused and I gwet an error.   The Error I got is :  

File: D:\Game\Bin\Gameplay\GameplyData.package Error: Data error (cyclic redundancy check)

it did not finish installing....I have tried to look up how to fix the issue and came across a forum that said to defragment my computer. I did that and it is still not working.  I would like to intall this expansion and not have to buy it again.  Please Help.

Did you try all the suggestions in the thread I linked above ?

I got a message similar to this when reinstalling the sims university. The message basically means that the disc drive is having problems reading the disc. And if it cant read it, it cant install it. This problem can be caused by a number of reasons, such as a faulty disc drive or a scratched disc. After hours of looking online for a solution, I eventually just gave the disc a wipe. Simple as that, it worked. Even the smallest spec of dust or smudge can cause issues reading the disc, so useless as it may seem, try this!

This link doesn't work at all.  I have tried three disks.  UGH it's so frustrating.  I had this problem with Island Paradise (2 disks) and Seasons (3 disks).  I hate to keep sending them back to EA.  Also, they suggested a digital download but origin and the download kick me out of my internet and screw it up so that doesn't work either. I will try the wiping the disk as suggested below.

thank you so much it really helped
