Psst... look at the log
WinXP, Pentium, 1GB - and she's one hell of an early bird!
Though the server could be on another system...?
@Debbie, sorry for the log thing, I didn't intend to sound condescending, I just didn't think about that then. Question: did you try running the command more than once, perhaps with a server restart in between? AFAIK the data generation code in PB 2.0.0.7 is no different from Arya's last 'official' release 2.0.0.5, at least I didn't touch it in my repackaging (and neither did Rapitharian in his, I assume).
(I do have a possibly related problem on my server though, where it crashes anytime I try to recreate the RunUO docs - it seems to hang at the bulk order system documentation, possibly an incompatibility with the custom O/W/L system I installed [Karmageddon's])
