Panda antivirus pro 2010-issues-internet connection/firewall

Hello. I have Panda Antivirus pro 2010 and windows 7 (64 bit)
I have had and still have a number of issues.

1. some months ago I had a low self-diagnosis problem that couldn't be solved by restarting my pc, so I did as Panda's little window told me: i uninstalled and reinstalled the product.

2. I uninstalled the program but all of a sudden, my internet connection was LOST! windows was telling me that there was an issue with my network adapter. however, when I finally reinstalled the program my connection started working! so this means, If I ever choose to uninstall Panda, I'll be doomed to have no connection? any explanations for this and possible solutions in case I need to uninstall the program?

3. some weeks now panda tells me I need to activate firewall. so it asks me to restart my Pc in order for it to be activated. although I've restarted it many times, it still says I need to activate firewall by restarting my computer!!!! however, when I check my settings, the box concerning the firewall activation is checked!!! this is my current problem. any ideas what's going on? is it really activated or not? am I protected???? any solutions?
