I have no clue how to fix my problem (won't connect after upgrade to Pro)

[no clue 2]

Hi
I have been using LW basic for nearly one year, problem free, two days ago i up grade to pro and guess what? it doesn't want to connect. I have a wall in front of my world, so i read your support threads but guess what i have basic skill in using my lap top , so far i did the test and it came back with working, i added LW in my firewall, my norton pro doesn't allow me do anything with firewall (i hate norton) so when i read your help i get lost, what the hell is unpnp? or any of the other stuff. Did i make a mistake by up grading, is pro only for people who knows how to use a computer, reading your forums i see many people suffer too. Is my best option to give up and use basic??????
