Nordvpn and AVG just wont work

I used NordVPN with AVG internet security about 25 days and everything worked well.
Now i paid for AVG Internet Security Unlimited and AVG PC Tuneup.
Internet Security and NordVPN worked well until I used the AVG PC Tuneup. This Tuneup messed mc PC and I begin to get BLUESCREEN when I try to use NordVPN.
I uninstall AVG PC Tuneup from my PC.
So I clean install Windows 7 and I just cant seem to get my AVG to work with my NordVPN.
I did disable AVG Internet Security program temporarily to check about Nord VPN is working. The answer is NO. I got Bluescreen again.
Than I uninstall AVG Internet Security and NordVPN works perfectly.
Now I have many times clean install windows 7 and every time I try to use AVG and NordVPN still getting BLUESCREEN.
Both work  seems perfect individually.
HOW CAN I GET AVG and NORDVPN WORK TOGETHER.
Any help or direction to look will be great thanks
