Here's what I did after getting stuck after the Ras Al Ghul gliding trials (like everyone else, after you do the glide/dive trials and you end up in the room, no assassins are there to greet you up the stairs, and you can't go past the invisible wall which appears to be SecuROM reacting to the trainer's presence/usage):
Start a new game. DO NOT start with the trainer active at all. Don't even open it.
After you first get the Batsuit on top of the Ace Chemicals building, alt+tab out, and run the trainer. Press F1 when you're back in the game's pause screen.
Then, just use the "99 Upgrade Points" cheat, NOTHING ELSE.
Immediately alt+tab out, close the trainer out completely. Back in the game, just glide to the courthouse where you save Catwoman and trigger the first auto-save checkpoint once you get inside. I recommend using the 2nd floor door.
Once you're in the courthouse and the game has saved, just ALT-F4 completely out of the game. Now restart the game, and go ahead and just max out your skills/upgrades with your points. If you do this, SecuROM doesn't detect the usage, and you'll have pretty much everything you need maxed out for the most part(armor, health, skills, gadgets, etc).
Now, you won't have infinite health, etc., but with everything upgraded from the start, Batman/Catwoman are both already pretty OP. I had no problems getting through most of the game on Hard with only using the trainer at the above one point in the game. Most importantly, it allowed me to get through the Ras Al Ghul fight and I finished the game. Am now enjoying it in the New Game+ mode.
Also, the game did NOT crash ONCE on my playthrough where I only used the upgrade cheat. On my previous playthrough where I used Infinite Health and let the trainer run the entire time, along with the upgrade cheat, I got crashes 20-30 min. at a time and never got past the invisible wall in the Chamber of the Demon. Hope this helps!
