Latest beta won't download

 From:  mickelsen
I tried to download the Dec. beta, but when I did it said that it downloaded the Oct. beta and that it has expired! I noticed that when it was downloading, it said it was downloading into the folder for the Oct. beta and asked if that was alright. I figured it knew what it was doing and said yes. If not, where should I tell it do download to? I've never run into anything like this before with any of the other beta downloads. Am I doing something wrong? Please help. I'm right in the middle of a project.
