Ghostscript

I'm running GPL Ghostscript 8.70 (2009-07-31) on Windows XP. I have about 100 PDF files I've attempted to run through GS, but I'm having font-related issues on two separate groups of files from two different customers. I'm not sure if the issues could be related. Here are the two errors I receive:

Loading Courier font from C:\Program Files\gs\fonts/cour.ttf... 2343384 986555 13583240 12261829 3 done. Using CourierNewPSMT font for Courier. Error: /rangecheck in --get--

Can't find CID font "Arial". Substituting CID font /Adobe-Identity for /Arial, see doc/Use.htm#CIDFontSubstitution. The substitute CID font "Adobe-Identity" is not provided either. Will exit with error. Error: /undefined in findresource

I've tried just about everything I can think of with fontmap and cidfmap. Does anyone out there have a solution?

I fixed the Arial problem by adding an entry to cidfmap:

/Arial << /FileType /TrueType /Path (C:/Program Files/gs/fonts/Arial.ttf) /SubfontID 0 /CSI [(Identity) 2] >> ;

Any ideas on the other problem with Courier?
