rstanek,

That is exactly what caused my problem at the beginning of Jan.  The accounting firm transferred the billing to my company and I was unable to enter new payment information.  After calls, emails, and promises that I was added to the list of users having this problem I never heard anything more from Intuit.  I finally called support once more and worked with a support tech who did more than tell me the problem was with my credit card OR that I needed to clear my cache, etc OR that I'd been added to the list.  We tried a number of things together and finally solved it. 

Try the following:

Go to your browser settings (ie Chrome settings)

--> Advanced

--> Site Settings

--> Cookies and site data

-->  Allow

Add the intuit site address (I added both intuit.com and qbo.intuit.com)

Then go to a new browser window (I used an incognito window), open QBO, and enter info in Resubscribe.

Voila!!!

(please note--I also had disabled my firewall and virus setting previously but this alone didn't seem to help.  Both were still off when they had me allow the intuit address in Chrome settings so not sure if that helped to make it work.)

Best of luck to you!
