Thanks for the reply Arno, I figured out the longitude issue. But I'm not sure what to do with the .cfg errror, yes I did add the folder to the library, the folder contains the BGLC_9 converted bgl file, and a folder containing the mapped textures, named texture.
The lines I edited are from my EM_BASE and EM_BASE_0 .asm files and are shown below respectively,
EM_BASE
DEFAULT:
OBJECT_0_START  label word
       IFIN1        OBJECT_0_FAIL, image_complex, 1, 32767
       ADDOBJ       OBJECT_0_SCALE
       SHADOW_CALL OBJECT_0_SCALE
EDITED:
OBJECT_0_START label word
    IFIN1       OBJECT_0_FAIL, image_complex, 2, 32767
    ADDCAT      OBJECT_0_SCALE, 8
EM_BASE_0
DEFAULT:
runway_base_top  label BGLCODE
       BGL_BEGIN 0800h ; version = 8.00
       TEXTURE_LIST_BEGIN
       TEXTURE_DEF TEXTURE_AIRCRAFT,  <255,255,255,255>, 11.112889, "2B2_RUNWAY.BMP" ; 0
       TEXTURE_LIST_END
EDITED:
TEXTURE_DEF TEXTURE_AIRCRAFT    , <255,255,255,255>, 1805.527747, "EM4_STITCH.DDS"	; 0
    TEXTURE_DEF TEXTURE2_NIGHT      , <255,255,255,255>, 1805.527747, "EM4_STITCH_LM.DDS"	; 1
    TEXTURE_DEF TEXTURE_AIRCRAFT    , <255,255,255,255>, 33.275646, "TARMAC1ALPHA.DDS"	; 2
    TEXTURE_DEF TEXTURE2_NIGHT      , <255,255,255,255>, 33.275646, "TARMAC1ALPHA_LM.DDS"	; 3
    TEXTURE_LIST_END
I would like to mention that I didn't paste straight from the poly tutorial, I didn't copy the tutorial figures into my own .asm files, I just don't have a copy of the originals, so I'm using the tutorial ones for reference.
Thanks.
