SBIE 1231 Initialization failed for process [C0000038 / 66]

Hello, and sorry, but I'm using the google translator.
I am trying to use sandboxie on a program, but I cannot.
The error messages are as follows.
SBIE 1231 Initialization failed for process [C0000038 / 66]
And
Only part of a ReadProcessMemory or WriteProcessMemory request was made. (299)

the program is a game my son uses, and would like to have it on my computer when he comes to my house. But as I don't know, I want to go through sandboxie. the name of the game is ACEonline.exe
