Is it possible that you need to right-click->Properties then on the General tab it may say the file is blocked for your safety so you click Unblock.
Also check where the file is saved. If it is on the root (top level) of a drive, often this can cause Windows to stop you using it as it gets a bit weird about using the root of the drive as a place to store/run applications.
where does this save go?
Prey saved games are placed, regardless of where your profile is actually set to, in:
C:\Users\USERNAME\Saved Games\Arkane Studios\Prey\SaveGames\CampaignX
Where you replace USERNAME with your PC username and X with the campaign number your saved game is running from. It appears the locations start with 0.
eg. C:\Users\Chiffster\Saved Games\Arkane Studios\Prey\SaveGames\Campaign0
I'm not sure what was in the save game file, but inside that Campaign0 folder you get folders such as:
That is the list of folders I have in mine.

As chiffster said, however this save is much more up to date with 99% of all psi powers, very few missing.
If you can a no cooldown would be great too, some of them have insanely long ones.
It's just possible (even probable) that the game just froze/crashed on you. I've had it crash three times thus far, all of them were when zoning from one area to another.
Yeah that is why said I would try to replicate it..so far not been able to so going to go with game problem not trainer..I was not leaving area into another..I was in the room and picked up gun..moved toward the table and boom..froze..
