Right run it as admin and also make sure steam is run in admin mode. Also Disable all protection programs or make sure the trainers ar in a folder that those protection programs do not check. This should help also. When the trainer is authenticating wait till its done that. Just another tip cause sometimes if you go to another folder right away it crashes.
if all of your trainers are crashing, IE 10 is probably to blame. See what version of Internet Explorer you have, if it's IE10 then uninstall it. if you have trouble uninstalling it refer to this Link for help.
