Renewal/Reactivation of PC Tuneup

I just renewed PC Tuneup & can't activate it.  When I go to my current version & click on HELP, it just says AVG PC Tuneup…, AVG Website, AVG Support website, NO reactivate or Register to click on to.  I tried download the new copy & get the message that it's incompatible with what I already have.

Hello Nancy,

The concept of existing PC TuneUp program is quite different as it can be activated only using AVG my account credentials and not with license number.
We have a product called AVG TuneUp - Unlimited Devices which uses AVG my account credentials for activation.
The product that you have purchased, uses the product key/license for activation.
Hence, uninstall existing PC TuneUp as mentioned (here) and to install your subscribed version, follow the steps as mentioned (here).
Feel free to contact us if you need further help.
