Craig's Brother dropped from Tooth and Nail

"Craig's Brother has been dropped from Tooth and Nail records. The message on the bands website states that the split was due mostly to financial differences between the band and label. Craig's Brother will be touring the states this spring in support of its latest (and last) TnN record, "Lost at Sea." Tourdates are on the bands' website."
Financial differences? Does that mean they weren't selling as well as MxPx?
