Nope, and i'm using the same card i already used to subscribe to another creator, there's still limit on the card too, but i've tried like ten times and always give me this error:
"This card is declined. Error code 0674. Please, contact support."
I've sent subscribestar an e-mail and am waiting for a response. But it's pretty odd... i've looked for people whit the same error and they say it's an error on the site and they didn't got any answer from e-mails to subscribestar.
