Avast also screwed up all my server setting in email and I couldnt send any email .
avast! didn't screw up anything. Everything that is changed inside your e-mail account settings is like it should be. avast! MUST change some settings in order to protect your account, and nothing is wrong with that.
You couldn't send e-mail just because you didn't set those settings properly. You need to spend some time on solving those problems, and not give up as soon as little (I will call it minor) problem comes up. There were hundreds avast! users that found setting those settings too difficult... so what ? There is always someone in avast! fourms who will help... And best of all, we helped a lot of people. Giving up on first problem that comes up and going back to AVG... I don't know... well, good luck - that's all we can wish you...
Btw, very-frustrated is not quite a nick name... it tells us that you in the first place didn't ask for help. You created your account with intention to tell us that you are unhappy... Let's say, someone, or everyone helped you, you solved all those problems and you suddenly became great avast! user - what would you do with that nick name ? Leave it like that ? It would look kinda weird... I suppose in AVG forums, your nick name will be VERY-HAPPY-AVG-USER... sorry I forgot, they don't have forums and they don't have forum support...

When i enter my number to register the product it says invalid. Ive copied and pasted it into the box so there are no typos, and re-registered 3 times but still nothing.
You shouldn't COPY/PASTE that number, 'cause sometimes you'll copy one space character at the end of the licence number. Just look carefully when you mark something with your mouse pointer, you'll see that sometimes (actually, very often) space character at the end of the line is copied as well. If you enter whole number + one space character at the end, it's not your licence key any more. It's completely different from original number you've got. So, you better type character by charcter, one at a time and it will work, I'm 100% sure. There is no chance not to work, no one used that number before.
