IRShell3.7 + Remotejoy4irs - Works But feezes and skips?? Help?Please?

Ok Well I Have Installed IrShell 3.7 & Remotejoy4irs Using The USBHost That is in the Remotjoy Folder.

I am Running Windows Vista 32 computer With Dual Core and 2.5 Gigs.

IM trying to Use Monster Hunter Freedom 2 As my game and It seems to work Fine Other than It constantly Freezes up and then It skips like 5-10seconds untill It Unfreezes.

When it does this the FPS dont change though.

Is this a Compatibilty Issue With the game? I wouldnt think so though Considering Ive seen Plenty Of videos posted on you tube playing this game without a hitch.

Any Ideas On whats going on?

Thanks

Can anybody help me PLease???
