[asdf-devel] Error writing some output translation

I am encountering the error below when trying to load-system from directory d:/foo/: Error: Failed to MAKE-DIRECTORY file C:\Documents and Settings\mitch\Application Data\common-lisp\cache\lispworks-6.0.1-windows-x86\d\foo\d:\: The filename, directory name, or volume label syntax is incorrect.(123). I am able to load-system systems I have downloaded (e.g., lw-add-ons, cl-pdf) which are in a different directory (d:/lisp/). I have fooled around with a .conf file in the d:/foo/.config/common-lisp/asdf-output-translations.conf.d/ directory but that hasn't helped. I'd appreciate any suggestions. Mitch Berkson
