I have started trying to brute-force it, but thought I would ask around anyway. At this pace, with 30 of my mining machines running a process, it will take about 1.5 months to try all of the a-z0-9 options up to 6 characters. I don't even know if that will cover it, so if anyone knows of a GPU-based brute-forcer please PM me. Or a way to run it not through simplewallet like the bitcoin brute-force options of extracting the hash and trying to generate a match. With the rise of XDN value it's worth my spending some time to work it out. Also, I am just stubborn like that.
I have the same problem. Would love to know the fix
