Check the System Log, it should have recorded the load. Alternately, if you have the 'System Load' Folder, search that. However, if the load occurred prior to your v9.x upgrade, it might not be there.
If you can search for a document in the load you want in the thick client, you can right-click and choose 'Properties', and look for the 'Partial Load ID'. You can search for message number 88 (Successful loads) and specify the doc name (in the numbers-and-letters format like 123FAA) inside the message text field (%123FAA%) to find loads that match.
Let us know if that worked!
