ok heres what i got (for the D13b5b9)-
D, F#, Ab, C, Eb, G, B
(notice how this is the same thing noticingthemistake got)

ok your notes were -

G#, D#, C, F#, B

a "G#" (or Ab) is a dim. 5 (this is where the b5 symbol takes effect)

so now you know where the b5 is -

a "D#" (or Eb) is the b9

so now you just have to tackle the "13" -

C is your dominant/flat 7th, because you need it in the formula for a dominant 13 or D13

F# is the major 3rd, which you need for any major chord

B is your major 13th, which is where the chord is extended to from the symbol

In your chord the 11th is out, this is not a big deal, because their are so many variations on chord forms that you only need the important ones.

The only problem is you have no root note. You have 5 notes, so it means your using 5 strings, see if on the string your not using you have a D near by. Another mystery is solved. Sorry I don't speak German, maybe I should switch out of Spanish when I get to high school :D .
