HistoryBank and the SP 24 hr symbol

["ndtrader" <ndtrader@xxxxxxxxxxx>]

Has anybody used HistoryBank to patch the BMI 24 hr SP symbol?
When I do it, I only get ticks from Session2, no ticks from the RTH session.
Other 24 hr symbols - ES, ND, NQ work fine.
Has this happened to others?  I may be doing something wrong.

Thanks in advance
