Our Tom Clancy´s Ghost Recon: Wildlands Trainer is now available for version 4792145+ (OFFLINE) and supports STEAM, UPLAY.
Our Tom Clancy´s Ghost Recon: Wildlands message board is available to provide feedback on our trainers or cheats.
"Run the trainer and disconnect from the Internet right after and before you load UPlay or game. If the game or even UPlay is running while internet connected it will crash to desktop. Steam can be online as it seems to have no effect. Uplay will ask you to log in since no internet, just tell it to restart in offline mode all the time and skip the achievement sync. Then use the trainer normally."
Always be sure to read the included readme in trainers. Not sure if you authenticated the trainer first or not, all you said is you are offline. Would probably need more information.
