I somehow doubt it.Most free precomputed hases on the net are generally 7 digit alpha-numeric.You might consider making your own if the situation warrants it though.Btw,did you try running your hashes through something like this? http://sarcaprj.wayreth.eu.org/
Also,if you think you messed up with Rcrack you may want to try WinRtgen..it's a window based freeware app:
