Oops that wasn't supposed to happen DEP fix

Question: Mabinogi closed on me with the following error "Oops that wasn't supposed to happen", what do I do?


Answer: In the past, people got this error for 1 reason pretty much. Now people are receiving it for multiple errors, so there isn't a global fix for it. But the original fix is:


Add Mabinogi.exe, Client.exe to the DEP exception list. You can also try adding HSUpdate.exe.


"control panel -> system -> advance system settings -> click settings under performance -> Data execution prevention, and simply add the client.exe to the list." Original Post on Forums
