I deleted the files, steam offline mode, and turned off internet but the trainer fails when I try it at main menu, in camp, and when loaded into a map. I get this error:
13:44:12: Found multiple processes the trainer can attach to. The trainer activation could fail if the trainer attaches to the wrong game instance. In this case please, first see if the trainer readme contains special instructions about this. Otherwise close all game processes you find in the taskmanager and try again.
13:44:13: Successfully attached to Back4Blood
13:44:13: Collect_Player, Script error in line 4: Cannot find aob for 'Collect_Player'
The offline keys for Aurora are created within Aurora in the Settings tab and are not the same the old ones.
