As I said in my original post, I have already tried multiple browsers, and did the private browser window for each one as well, and I still have the same problem.  I have also contacted the customer support team (by doing the call-back method) three or four times now, and each time the person looks through the whole investigation and ends up telling me "it's a known issue" and there is no estimated time for fixing.  Clearly, it has been fixed though for some, since Janelle above stated she had the same issue as me and it was corrected.  (BTW...thank you, Janelle. I called and offered the information you gave, but was told that wasn't my particular problem right before I was disconnected.  So I will be calling back to see if they can investigate it further.)  

Also... my issue isn't just the "Error while exporting transactions..."  This is a relatively generic error message, so I imagine it pops up with a variety of different issues.  It is highly likely that the investigation tied to that error message was closed because of a resolution that has nothing to do with my issue at all.   Typically, when a client calls with an error like this, I would go to the export settings and either fix whatever category was missing or wrong (OR for a few clients it has shown that the connection had been lost and I needed to re-establish the connection.)  Unfortunately, when I click to edit the Export settings in Payroll Settings, I literally see nothing--a completely blank white page. So I can't check the export categories or reconnect anything.  I'm just getting really frustrated because everyone keeps suggesting things to try that either I have already done, or I can't do because I can't get into the export settings.  I can't help my client, and I'm tired of telling her it's a known issue and they're working on it.  I think weeks without export function is kind of a big deal, but I feel like it's not being treated that way.
