It happened to me with my last 2 attempts. I again retried after couple of days and they worked. I never had issues with SS cards in the past. Not sure whether any others had similar experiences.
Whatever funk those BHN cards were in for the past week, seems to be over now. I don't know if it was a glitch or enough people complained, but I could do 4x200 with GE/DE/SE back to back for past 2 days.
