^ first, I assume you've followed the instructions mentioned in the Readme. The gear list "just" prepares a list of weapons/equipment, which can then be used in #translu's unlocker table. (iow it does NOT unlock anything itself)
(if something is unclear in these instructions, do tell which part)
that said: if the unlocker returns an error, then there is not much i can/will do. apart from saying that your game_exe should be the final version (I think the table works for both standard/extended vs <= which vs do you have ?)
And if you can't see the items in the table, you can (obviously) not make the "link" between my item_list and the unlocker. Iow you'll need to get the unlocker working first (DO follow the instructions in the readme in that regard)
tip: if not working, quit both apps and then relaunch/try again... (do not attach my table initially)
ps1: make a prtscrn of that error and post the image_link here
ps2: I believe #translu indeed has retired some time back; such is live i'm afraid
