I can't activate my new license and the program won't open

I'm hoping someone can help me.  I installed 2016 on my computer. The program won't open at all.  It just stays on the screen "verifying license". Should I try to reinstall the program?  Is there something I can go in and fix to get this working again?  I had to buy two last time to get my software to work so I expect I'll have to do the same maybe. 

Thanks for your help.
