[GNC] Amex won't let me access QFX data without a Quicken Account

[Steve Cohen]

I've recently picked up Gnucash after letting it slide for about a year.  I
want to download data from my American Express Card account in QFX format,
and they won't let me do it without "deactivating and reactivating" my
Quicken account.  Quicken doesn't own my data, I own it.  I don't even have
Quicken available to use to deactivate.  Amex technical support is
useless.  What are my options?
