WinTV v7.0 2.5a doesn't show the version info on the first configuration page as it has been in recent versions/releases. Neither is it on the 'About' page, it just says 'Default'.
Thanks for the quick response. I'll do some more investigation.
I'd re-booted several times so I've re-installed and it's all OK now. There must've been a hiccup on the first install that I didn't spot.
Please close this thread as resolved now. Thanks everyone.
