Adobe distiller could convert whatever PS files that I had while on Win XP but the version 9 installed on Win 7 selectively converts into PDF. Not sure why some files are working while others are not working.

Be sure that the Acrobat 9 install is fully updated.
Be well...
Installation of Acrobat gives you the "base line" dot release.
For Acrobat 9 that'd be '9.0'.
Then you install each available "update" to bring Acrobat 9 to the last dot release (9.5.5). Note that the Acrobat 9 product family past into "end of support" mid-year of 2013.
For the list and download link for each dot release update to each version of Acrobat
