any help please , thanks in advance .
Trainer may not work for GOG version, but going through the troubleshooting guide never hurts Link
always right click on the trainer and run it as administrator.
make sure the trainer you are using corresponds to you game version number. If the game version number is higher than the latest trainer version number, you will need to wait until an updated trainer is released.
security software can interfere with the execution of the trainer. you may need to disable/uninstall all anti-virus, firewalls and other security software and/or add the trainer or the folder that the trainer is in to the exceptions list on your security software.
IE 10 can cause problems with many trainers, if you have IE 10, uninstall it for troubleshooting purposes. More information on uninstalling IE 10 can be found here Link
please make all trainer related posts on the official trainer topic made by PWizard(and sometimes by caliber or 0x90). The official trainer topic will be a sticky topic, meaning it will always appear at the top of the message board in bold red letters.
this policy is in place for the convenience of the members as well as the staff in effort to have all trainer related feedback, support, and problems in one location. the policy is clearly stated when making a new topic Link and all moderators have been instructed to delete these types of topics on sight.
obviously, this policy is void if:
-there is no official trainer topic
-the official trainer topic is locked
