From someone who had the same error from the steam forums:
I tried deleting everything except for steamapps and the exe and that didn't work.
I just changed my download region to Brazil and tried to install again and it finally picked up all the files I had on my hard drive. Strange error since I had tried quite a few different download servers in Europe. I don't see how changing to one on a different continent would fix this.
