Hi Ronan,
Do you have VM TVGo on your PC/laptop? If so please try the following:-
Open TVGo and go to the Live TV guide and select one of the Sky Sports channels. This should then show a clickable icon in a small red box, ' Watch on Sky Sports' - clicking on that should reveal another red clickable pop up box, 'Exit to watch'.
Clicking on that will direct you to the Sky Sports web page where you should then see a prompt, 'Install the Desktop Player' .If you haven't already installed Sky Desktop player then click on that prompt and the page will be redirected so you can download the desktop player app.
If you have already got that installed then click on, 'I have already installed the Desktop Player' instead and then click on 'Continue' This should then open a Sky Sports pop up browser window to play your content.
You should also test the Sky Sports app on an android or ios mobile/tablet to see if it's working, and any problems use the VM TVGo app, click on a Sky Sports live program and then click on the pop up to see if it opens a working Sky Sports app.
