If you have not used Dropbox to download files I have uploaded the 2012 KOP so you can check out the process and how long it takes to download. It is 130 MB and took about 30 minutes to upload.
Also, I have added all the email addresses from teams who requested Dropbox access. You should have received an invitation to join the folder. If you have not, please email me again at firstname.lastname@example.org and I will resend the invite.
