Thanks for your reply CharleneMae_F
I ran all the steps in the link you mentioned as step 3.
Step 1: I downloaded the CC transactions again for period May, selecting download type Quickbooks, which defaults to QBO. No error messages were triggered.
Step 2: I did not get any error messages when download my Capital One transactions.
Step 3: I already had tried to switch from Express to Classic mode in Change Bank Feed Mode. It did not make a difference, I still get the same error
Step 4: I created a new company file as suggested, I had not created the Capital Once account, just tried the import (as that normally ask what account the transactions should be assigned to), but again, I get the same popup.
I just have this one CC, thus, can't try another QBO import.
Would you have a sample QBO that I could try to import into the test company?
I am still puzzled why it worked once, then all subsequent imports triggered the same error right after starting the import.
