Well, You've taken some of the most common steps given. The only things I can further suggest are the following;
- Try several other injectors to see if it is a problem there.
- If everything is injecting correctly but not showing up in game, then the likelihood is your operating system is not compatible with the hack, or the hack is currently detected ( in the sense that the features are disabled, typically box hacks or hot keys ). A hack can be detected without triggering an Xtrap error.
If this is the case, please keep checking back for new updates and releases
