Dolphin Error

[wishba]

Hi. I downloaded Dolphin awhile ago working quite smoothly for months. Zelda TP ran at 90-100% in most dungeons, but plummeted to 46% in Hyrule Field. All of a sudden I get an error: "Could not set working directory (error 123: *file name, directory name or volume label is incorrect*). The asterisked may be inaccurate, just a translation, since the rest of the error read as korean. The strange thing is that it happened roughly same time as my IE stopped downloading things. Games on the list were also removed, and cannot setup a new file. If I try to directly open an iso, it will loop back to choosing a directory. Any help would be greatly appreciated.
