I can't activate my Premier, after reinstallation AVAST?

I had many problems with my AVAST antivirus and other sub software. I choose to remove and install software again. Now I saw that my license for Premier wasn’t started? How I can activate Premier now? Also I have a problem with secureline Amsterdam. I must do secureline with Frankfurt in Germany than my computer is working well, other wise I have blue windows screen!
