Error unable to create a cue file???

[KOKIDD]

I am trying to patch Grind Session US version.This is my first patch and I've used Cdrwin to make back ups of PSX copies prior and CDcopy works fine also.I have followed the FAQ's and some graphics step by steps instructions so the settings are correct as far as I can see.But since this is my first time creating bin and cue files so they can be patched.I may be doing something wrong or my burner and CD rom maybe incompatable with this software for this process???Thanks in advance for any help on this...KO
