Unfortunately, the space character is a valid character in windows passwords. Space is included in both the charsets and examples on the rainbowcrack project site (http://www.antsight.com/zsl/rainbowcrack/).
Hopefully this is simply an error in typography when listing the charset for this project, rather than the actual omission of the space character from the set.
Sorry I cannot test this, I havent got the 120GB free on one machine to do so.
Also, I am curious why the rc project page says that the charset above (plus space) should be 64 GB, rather than your as built 120GB.
Thanks!
