trouble with Tile Changes

[Schneestern]

by now my friend and I are unable to solve one Problem: Tile Changes. We do not use tiled, cause we simply prefere Mappy and so. (And tiled couldn't solve my problem... I've tried it... :/ )
I was going through Arch's Boot camp Ep. 16 and the "tile changes"-post in "event hacking for dummies" (I've read/watched it many many times), but I still don't know, where I'm mistaking.

funfacts: I've got one ROM, where the door of my testmap opens, but it is replaced by a tile that I didn't choose. (even if I change the reference code of the tile I wish to use, the door is simply replaced by the same tile)
If I use a other ROM (a earlier copy of the ROM I mentioned) and assemble the same txt-files, then the door-tile won't be replaced (but my Thief is able to use the "door"-order and his Lockpicks durability decreases by 1).

here's the relevant passages (well... I think/hope that these passages are relevant xD ) :

The MapChange-file:
________________________
//Prologue Map Changes
#define TileMap(TCN,X1,X2,L1,L2,TilePointer) "BYTE TCN X1 X2 L1; BYTE L2 0x00 0x00 0x00; POIN TilePointer"

ORG 0xC9C9CC+(4*0x0E)

POIN TileChanges

ORG 0x8CE1D20

TileChanges:
TileMap(0x00,0x09,0x07,0x02,0x01,Portal)
TileMap(0x01,0x09,0x07,0x02,0x01,Portal)
WORD 0xFF
WORD 0x00
WORD 0x00

Portal:
BYTE 0x24 0x0D 0x24 0x0D

MESSAGE Map changes end at offset currentOffset

and the location based events, from the event-file.

___________________________

LocationBasedEvents:
LOCA 0x3 [0,8] 0xF
DOOR 0x00 [9,7] 0x10
DOOR 0x01 [10,7] 0x10

ORG 0x8CE1D20

Notice how in the same event file, there's a similar line here?

ORG 0xC9C9CC+(4*0x0E)

You'll see that you don't actually need (and shouldn't use) the 8 at the start.

Try changing it to:

ORG 0xCE1D20

The EA doesn't need the 8 at the beginning. You might be telling the EA to write stuff to an address that doesn't exist.
