Thank you for providing the DLL bulldog. I was able to locate and fix the issue. The updated trainer will be posted soon and can be used with GOG version.
Awesome! Thank you @0x90!
I just downloaded and tried out the new trainer and it is working with no problems at the moment.
You can use the editor to change the reputation value or enter a negative amount in the "modifying value" column of the trainer option and then use the hotkey.
Thanks 0x90. I forget about entering a negative value using the editor. You guys rock.
