Quicken will not establish an account with Morgan Stanley

Question

I have 15 separate accounts with Morgan Stanley; i recently upgraded to Quicken 2020, version R31.12. I successfully imported and established 13 of the accounts, but two accounts, both trusts, will not link. I am using the Add Account function in Quicken, to establish the connected account, but when I attempt to sign into Morgan Stanley to connect the account by clicking the "Connect" button, the cursor simply "loops". The account number turns blue but nothing happens.  No error message occurs. I attempted to establish the account with a Morgan Stanley IT individual, who advised that he could see me attempting to establish the account, but there is nothing on the Morgan Stanley end preventing the account from being established. Morgan Stanley advises to contact Quicken. Again, no error message.
 Thanks for any help.

Hello @SLKynerdc Thank you for the response and for letting me know the results of the test file. I would next return to the original file and run the Validate & Repair tool on the data file from the File menu > File Operations > Validate & Repair option.

In the Validate File window that opens, click the top box to "validate file" and then click OK.

When the validation completes, a data log will open in Notepad, please let us know if any errors or issues are found/repaired, and when ready close and re-open Quicken.

I established the quicken test file, and the account DID download properly!

Do you have a suggestion as to what to clear on the primary file?

Thanks so much.
