Quicken 2012 Does Not Work With Amplify Credit Union

Hi, I was a Quicken 2009 user who upgraded to 2012 version. I am the owner of a Financial institution and the transactions are not updated in a single step. I tried to deactivate the account as recommended by another post, but that too didn’t work out. I have downloaded my transactions from the Amplify site, but I’m unable to use the current version of Quicken.
Please help me by giving instructions to disable and enable this account so that it works with Amplify Credit Union.
