Enable the trainer, once in game, go to your inventory screen. to edit money & eridium coins, just change values to whatever, move your mouse to a different item in your inventory and it will change.
to set your level/xp after changing it in the editor. click on a different setting, exit your inventory menu and play tell you gain some xp and it will apply the changes from the trainer. (if you dont pause game, just change level/xp in trainer, select a different setting after changes are made, go gain some xp and it will work)
Trainer works great, got all characters level 50 max stats and unlimited credits for each characther!
Thanks for your help! I didn't think to "gain XP" or to switch back and forth between inventory items as a means of activating the changes. I was just idle a safe zone expecting the edits to happen out of thin air.
I read your comment only after I installed the update and felt a sense of regret, but the trainer works fine with the update.
