You need to go to the old site and retrieve it. Sooner the better just in case Amazon gets rid of it for good. https://www.mturk.com/mturk/dashboard?doNotRedirect=true Got this from someone in Reddit: Go there and then to the Hit DB at the bottom. Don't bother trying to update - mine didn't work and someone else here had the same experience so I think that's not working anymore. But if you click "Create Backup" the script will download the file you'll need to import to the new site's version of Hit DB. Depending on your browser's settings, you may get a "save this?" kind of popup or it may just automatically save the file somewhere (wherever your browser is set to save those; mine go to the desktop so I can find them easily). The file will have a name like this: hitdb_20171216.bak You can open it in a spreadsheet but it doesn't look like much. I can say that the one I did today, just to test these instructions, does look like the one I grabbed yesterday, so I think it should be okay. I suspect it will be out of date, though, with nothing after yesterday (12/14). You just need to save it somewhere until the Hit DB script is working on the new site. Just one more thing: There is another kind of file you can download from there, and that's the CSV. If you want to actually see your hits and some information about them that's the one to grab, but - like the .bak file - you'll need a spreadsheet to open it, and you may need to play with the column widths and maybe re-sort everything. But it's pretty much just for your own use (I use it to update my own hit database; or at least I did ). The .bak file is the one that's needed for importing. Save it until you find another Hit Database to import it to.
