As a follow up...
If you are going to uninstall and re-install then make sure you create a backup of your files. After that, perform a search for Intuit or Quickbooks on your C drive. Delete all the associated files and folders so that the install does not use any residual files from the previous install.
After you re-install the software do the following:
Reboot the computer
Start QB and login
Attempt to setup the feeds again. If this does not work then perform the updates and try again.
What I found is that the updates are creating part of the problems which we just stumbled upon when we tried the feeds from a different computer in the office.
Realize this wastes a lot of your valuable time and is frustrating which is why after 24 years of using QB we are done after this year.
Good luck!
