I have 32GB RAM, so that shouldn't be the issue though.. but idk, maybe 1 of them are bad.
Also have NEVER happened anywhere else, only with LastHope.
Well then, the only thing I can think of, is that you've disabled the page file entirely. Some programs require the windows virtual memory to be activated, in order to function properly.
If thats not it, then perhaps screenshot that error, and maybe someone else can help you. Perhaps the dev might look into it.
Btw, if one of your ram sticks was bad, then you'd be getting BSOD's or restarts, not a simple "out of memory" error in one specific game.
I VERY MUCH DOUBT that you've got faulty memory issues, but if you want to be sure, just check them with MemTest 86+.
