Supporter - Change default text

Hey all,

I know everyone's busy with the 3.0 upgrade (I'm doing some major testing this weekend as well), but I have a (hopefully quick) question.

I was trying to modify the default phrasing on the subscription page in the Supporter plugin. Currently at the bottom of the table there is the phrase:

Depending on your payment method it may take just a few minutes (Credit Card or bank funds) or it may take several days (eCheck) for your account to be activated.

I've found two places in supporter-framework.php with supporter_payment_message (lines 1152 & 1204) that quote this string. I tried simply replacing the text with my own, but all pages are still loading with the default text. After searching for awhile, I can't find any other reference that would keep this change from happening. Ideas? Solutions?
