For the past 3 days I have been having problems downloading my transactions into Quicken. It is only one bank which I am having the issues. I contacted my bank this morning and after checking my accounts they found no reason on their end for the CC-503 errors. So it definitely is a Quicken issue. I have also contacted Quicken Support for the last 3 days, but they offered no remedy for my situation. They also had me deactivate and try reactivating the accounts which was unsuccessful. I have cleaned my computer of all Quicken files, uninstalled and reinstalled Quicken. I tried creating a new file to see if I could setup a new file for my finances, but I continue to receive the CC-503 no matter what I have tried. If anyone knows how to remove this error I would be grateful to hear from you. 😐️
