Sorry if I misunderstood anything but...
Can I have my money back now and at least I am glad I did not spend the $5000.00 on your software I had planed on....
So you spend money on something and don't want to invest time in learning to understand the application or learning how to trouble shoot?
First you say you have mailed "sells" 3 times, than you say you have mailed "support"... There is a difference between them. Where did you send the mail to?
Then you say " you have to buy a lot of copies" but in a next reaction you say it is not you who does the purchase.
You say "I have tried uninstalling the things you asked for" which means the uninstall wasn't succesfull.
I can go on and on, but basicly it comes to this imho:
You are expecting a "delicate" application to work on a "delicate" system to work right after installation without changing a setting or anything else and without having any knowledge about the application?
You are forgetting that the home edition and the server edition are quiet different. A network is really something else than a stand alone system and you can't just aspect the server edition to work like the home one.
It looks like you installed the server edition and run into some (little?) troubles. I can understand that it can be frustating when you espect something and it isn't happening right away. I've had the same thing several time in the almost 25 years I am working with comps. But problems happen, you just need to spend a little time and efford to solve them.
Don't give up on Avast so easy. (Walking away is the easiest way, remember) Look at it from the bright site!!! Norton didn't gave you any support at all, Vlk (and I am sure others will also do if needed) right from the start!
Have some patience and follow his lead. I'm sure your problem will be solved and after that you will be very pleased with Avast.
Good luck
