Question about TexER for ripping

[Mr. Jones]

I'd about a specific game they had ripped. Unfortunately, they didn't have the sprites anymore, and they recommended me using the program texER, to extract them. But when I try to open the program, it opens briefly and then closes on its own. Does anybody know how to solve this?

I'm trying to rip the portraits and art out of Eternal Poison for PS2, and any guidance would be very helpful.
