You should have received an e-mail with instructions detailing how to correctly download your file.

Somewhere in the e-mail should be a link to your file as well as a login/password appropriate to your file. Click on the link and enter in your login information. Most files will be in the .zip format, so make sure you have a decompression utility such as winzip. After it promts you either to save or open it, choose "save it to location...", rename the file(please be sure that if it is a .zip file that the .zip remains at the end), and choose a location on your computer that you want to store the file. All you have to do from there is run the decompression utility on the file and you are done.

If your company has an ODC account, you will recieve special instructions on how to utilize your account.
