Resident evil 2 freezing problems

i am new to using emulators and my friend set this one up for me mainly for FFVll. I decided to download resident evil 2 dual shock edition but it always freezes at the gun shop and i tried hitting esc and resuming but it was still frozen. My computer is a new Alienware M17x maxed out all except the graphics card which is only 1 Gb. The plugins im using are psx emulation cheater 2.5 with pete's openGL driver 1.77 for the video and eternal SPU plugin 1.41 for the sound and ePSXe CDR WNT/W2k core 1.7.0 for the cdrom. What can i do to fix this problem and i am not very technical with this stuff so i not really sure what im doing.
