Betting exchanges use TLS 1.2 for all network connections. This means that you need to update your operating system as bot is unable to get data from Betfair and display it.
You must have Microsoft .Net Framework 4.7 installed on your computer. If you are unsure if you have it then you can download it from Microsoft web site:

Windows 2008, 7, 8 and 8.1:
If you are using Windows 2008, 7, 8 or 8.1 then please follow the steps indicated via
https://manage.accuwebhosting.com/knowl ... ows-7.html to update your TLS version to 1.2 as earlier versions are no longer support following a release this morning.
TLS 1.2 isn't enabled by default in Windows 2008, 7.0, 8.0 and 8.1 and this is the likely cause of the issues you are experiencing with various software applications.
