When trying to upgrade my RV016 router to version 3 I am getting a Bad Upgrade File! Please input a correct file. I used the upgrade tab from the router and even tried to use the tftp server from the linksys website. I am on version 1.2.3. Should I go to version 2.0 first but if so, where can I find that version since the cisco site has only the version 3.019.
