I believe this question was just entered over email. Here's the full explanation just in case.
To change the credit card associated with your subscription you would need to follow these steps:
1. De-activate your current subscription (you can do so via your Subscriptions page at http://twittercounter.com/pages/subscriptions).
2. Wait until your subscription expires (one month after the last payment).
3. Re-subscribe with your new credit card using our signup form at http://twittercounter.com/pages/premium.
Note that any data we have gathered for your Premium subscription will not be lost when you de-activate. Once you've re-subscribed you'll automatically have access to it again.
