That solution worked! I am using the latest QB update (version 2017) and it is bizarre to have to deactivate the bank feed for the account in order to be able to import the QBO file. I tried everything, including deactivating and reactivating several times and nothing worked. There needs to be a patch to this offered to allow you to work around it so you don't lose hours of time scratching your head trying to reestablish a link to an existing account just because some linkage aspect has changed.

Thanks for the suggestion.
