Trial Version Installation Issue

I was given the link to download the trial version of the software by a member of the sales department. I went through the entire installation process and even received a license file via email. But when I open the Prime 7.0 software, in the File-Options it says no valid license found and all the functionalities are locked down. I am unsure how to solve this issue. This is what is seen in the license options:
