checked that. while the folders are, for some reason, marked read-only, the files aren't. after transferring my old settings files to the new installation and firing up AH, the stick mappings were blank, as if my .jsm files weren't there. I am able to make and save changes though, so the files are accessable... I was thinking it might have something to do with the fact that the old installation was on a fat32 filesystem, and the new one being ntfs causing some sort of wierd permissions issue, but that wouldn't explain why a newly downloaded file of murdr's head positions wouldn't take. I think I'll try reinstalling and transferring old files over one at a time...
