It is the worst trainer that is very difficult to use because of the random key assignments.
That is not the trainer's fault its an issue of Aurora. The trainer just has too many options with hotkeys so Aurora starts to assign hotkeys it should not, like "LeftShift". I will fix this in next Aurora update in the meantime please do what Devil suggested and just reassign the hotkeys (or right click and remove them)
Note that if you already HAVE used the trainer before and then more options get added. Aurora will respect your SAVED hotkeys and only set hotkeys for the NEW options. In which case hotkeys get out of order. This is an expected behavior. If you find this annoying then right click on any hotkey and reset all hotkeys.
