The vendor suggests that you download again after deleting the cookies of browser and removing the temporary files. If still having troubles, contact them for support:


When your software is due for renewal, a message should be sent by the vendor to your Middlebury College email address outlining the reactivation process. If you misplace your serial number at anytime, you can look it up by logging into their website again.

Frequently Asked Questions


Absolutely. A professor can install the software on a home computer. The software can be installed on home computers and school computers, or on many school computers. The same holds true for students. As long as they are covered by the site license at all, which means that they have a valid email address at your school, they can install the software on as many computers as they want.


Yes, the software is available for both Windows and Macintosh users. You will be sent serial numbers for both types of computers and you may choose which one to download from the Cambridge Software URL. Are Manuals available? Manuals are available to download in the form of PDF. They are available for download from the same site.


We expect that most schools will renew their license rather than let it expire. If your license expires, you will only lose the ability to create new data and to edit existing data. You will still be able to view any data you had created while under the site license.


The Annual Site License allows you to use the latest version of the software, regardless of when that version was released. Each user will have to download and install the update, of course, but they are certainly allowed to do so under the terms of the license.
