Hmm, I may be just getting confused with the pin mapping of the 7segment display.  
The display has DP segments,  the pins on the side nearest to those DP segements, the left-most one is Pin 1. Correct?

When looked at from the front, pin 1 is the bottom left according to the datasheet linked from your first post. There is also a slim possibility the display you have is connected differently (it won't be the first time specifications have change without notice) so follow CrossRoads advice and buzz the pins out to confirm.
