R help - Apr 2006 - JGR problem

I just installed JGR version 1.3 and I am having a problem. When I try
to load the library RQuantLib I get an error message. The same program
runs perfectly well when I just run rgui.exe. I have pasted the screen
below. The version of R I am using is 2.2.1.

Thanks for any help.
