Cymatic is now in the process of ending support for Windows XP and thereafter will only work with newer versions of Windows such as Windows 7, 8, 10 or Windows Server 2008 SP2 or later. This is because Windows XP does not support the latest security protocols.
This change is being done in response to a sudden change of security protocols being implemented at the Betfair exchange.
If you are using Windows XP and aren't ready to upgrade it or buy a new PC, you might like to consider trading remotely on a virtual private server hosted in a data centre. There are even free servers available, so do contact me on the forum if you'd like a little advice on that.
With kind regards,
Gavin
