Weird, I'm having the same problem. And I thought I already activated it yesterday.

A prompt reply from NewBlueFX tech support:

Sergio, the serial number is entered during the installation process.
Once installed, simply open Vegas Pro 11, add the titler to the
timeline, and start using it. There is nothing else to do, except use
it, after the installation process is finished. You do not need to do
any additional activations.

Here's the deal with NewBlue Titler Pro:

1. Run the installer
2. Enter the serial number you received from Sony during the installation process
3. Finish installation
4. Start Vegas Pro 11 and start using the titler

There is NOTHING more to do. There are no other activation screens to go through!

I activated it, I'm 99% sure. Yet I'm having the same problem of Titler Pro asking me to activate it when I open it, yet the Activate button is grayed out.

It's not really asking to activate - it's asking to REGISTER. We're working on this for the next update.
