Purchased Office 2010 Pro download. I installed the software and it worked for exactly 1 year. Then received a notice that the software could not be validated and therefore would shut down. I've tried repair using the original install download but it does not work. I've tried calling the customer service only to find out the number is no longer in service. And I have also e-mailed customer service. I received a return email that said evaluesoftware closed in May 2014. I guess I am screwed. Never again will I buy an expensive product like MS Office as a download. I will only buy directly from the publisher.
