Hi Stuart,
Sorry to hear that. No your subscription hasn't run out, I checked the payments from you and it is all looking fine.
Please describe the exact problem or error message, thanks.
Also please confirm if you have changed your Betfair account or are trying to login to a different Betfair account (not the one that you originally used with Cymatic). I don't need to know your Betfair usernames, just whether you've changed it.
Kind regards,
Gavin
