I get the same error message (Datasource Error: "_logo.jpg") using 7.2.5. The Fares/DRS method still works but does not give any of the BA flights I am looking for. Any workaround for this?
EDIT: works for me now (Fares/PSH) - no longer getting the "datasource" error. Installed some Windows 8 updates, rebooted the computer and waited an hour or so. One (or none) of those must have helped
