Bank Feed Stopped working: Account name change or Electronic Payments

Hi all;

I stopped receiving transactions in my bank feeds a few days ago, however its status says 'Bank Feed Ready', im wondering if one of the following might have caused it;

1) I had the bank change the name of our accounts.

The Account Number and BSB is the same, so i didnt really think about it effecting the feed, but maybe it checks account name as well ?

Will i have to delete the feed and add it as if its new ?

In the meantime, if i manually import transactions, am i going to get duplicates when the feed starts working again ?

2) I tried to setup electronic payments (without really understanding them)

I entered the 'bank file' details and did a test transaction, could that have somehow effected the feed ?

I can't workout how to delete the bank's details, the link to enter them only came up because it wasn't working.

Thanks
