I've recently upgraded from v26 to v27 and reinstalled EIR as instructed.
If I generate a new report in Excel, it works fine, so I think the data links are ok.
However, if I click on 'Refresh' to get updated data, after a few seconds thinking time, I get an 'Error Executing Report' error box with the unhelpful message 'One or more errors occurred.'
I can't get a single report to refresh.
Many thanks, Ian
