They sent me a new license but they said it will not work with the new software!! I need to continue to use the old software!!
Why do I pay for software maintenance if my license will not let me use the new software and still have access to the same function as the old?

The Exchange portion is not accessible in the new software with my current key. The SMTP scanning is gone.

I have read the agreement and it says that I am entitled to the upgrades, so what gives?

3. Upgrades and Updates
Upgrades and updates of the Software shall be provided to you by AVAST during the term of the license indicated in the Documentation or other transaction materials made available to you at the time you purchase the Software.
You will not be entitled to receive any feature or content
I want what I paid for which is when you improve the software that I will get everything I had in the old software.

This is just a bait and switch tacit.

AVAST is not honoring it commitment to it paying customers.
