OK. Usually when people report this sort of issue, it's because the Pro registration hasn't worked.

Glad it's sorted anyway. Can you tell me what the problem actually was, in case it helps others with the same issue?

Cheers, Dave.

Next to 'Televzr' at the top left of the program window, does it say 'Pro'?

If not, that's the problem, although I thought that even the free version would download up to 720p.

Does it say 'Pro' next to the Televzr logo, top left of the program window?

If so, you must be logged into Televzr OK.

Are you trying to download from YouTube?

If so, are you logged into YouTube correctly?

I wouldn't have thought that you actually needed to be, but you never know!

Have you tried downloading from anywhere else?

Does it still have 'Pro' next to the logo, top left?

If not, I guess it's become deactivated.

Try re-registering it again using the account icon top right.

Make sure you use the e-mail address that you registered it originally with.

You should get an e-mail to click on a link to re-register it.

HTH.

Good to hear, I hope it now keeps working for you!

It's a great program (when it works).

Cheers, Dave.

Sounds like it's not activated.
If you click on the account icon top right, you should be prompted for an e-mail address.
Make absolutely sure that it's the same one you used when you bought the Pro version.
You should get a message sent to that address with a link to click on to activate the program.

Thank you Jovey, that's really useful information and I hope it helps others.

I've never had any problem myself, I've been using Televzr Pro for quite a few years now on a lifetime subscription, and it has always worked (touch wood!)

The Pro activation process has always been very unintuitive though, and it's great to have it explained.

This is not helped by the fact that as far as I can see, the Televzr developers never respond to problem reports, which is very poor. It is a good piece of software though, and at least in my experience, it works very well.

Cheers, Dave.

Are you sure it's not just asking you to activate it?

Just put in the e-mail address you registered with.

There is no activation code.
If you log into the app with the e-mail address you registered with, it should work, or prompt you to activate it.

Have you actually tried logging into the app with the e-mail you registered with?

The procedure is not at all intuitive.

When you log in, you should then be sent another e-mail with an activation link.

I've been using Televzr Pro for several years now, and it's never been a problem, so I would disagree that it's a scam.
