Unable to code LCM on e39

[SNIP]

Hi. I'm new to posting threads, but I have an problem with NCS expert and coding my LCM on e39, Car is 1997 523i.
When I load a profile in NCS expert and go through the normal F1 and F3 "select chassis "e39 " procedure, then "back" and I could be able to select the module that I want to code. Well. I can code every module except the LCM?
I can pick LCM from the list but when I change it to codierdaten_lesen or if I have pre coded the lcm in "BMW coding tool" and use sg_codieren, I can't. It gives me this. "Der codierindex folgender steuergeräte ist Für diesen Codieraufrag nicht zulässig: LCM 15"
I've tried to google this, but never came across this problem.. Maybe I'm just an newbie, is there something I'm missing from?
Thanks in advance!

Is it a replacement LCM?

No it isn't, I think it is the original one
