I have two drives in the HTPC. C: is primarily for programs, system stuff, and the user directories. D: is where all my media is. I created a new folder on D: for the MyLibrary files and created the three sub directories. I setup the Config.xml with the appropriate paths (and checked them three times). Every time I run the x86 batch file I get an error that Java couldn't create the directories.
If I change the config.xml to point to a directory on C: everything works fine. I'm using XBMC-SAGETV with folders on D: with no problem, and all my other XBMC stuff works there fine.
P.S. don't worry about all the other weird series stuff. I was trying to use the Daily Show plugin (since the Hulu one still isn't working again even with the new librtmp), but it doesn't use standard naming conventions.
I also tested this with the Hulu plugin, and I do get all the right stub files and stuff added to the library, you just can't actually play them...
