Ecclesia and the M3 Sd card problem

Hello!

I've got a problem here;
I tried to play OoE, but it won't load on my nintendo DS.

This is how my DS runs:
1). you see 8 pictures, one of them is a game-controller;
2). when I press the controller, I see the castlevania game (It even shows me the official picture that goes along with this game)
3). there are two ways of starting a game: by pressing start (open demo) or by pressing a (open game)
4). after step 3 you get a different screen where you press a or start (both have the same effect now) to start the game...a red bar can be seen showing you it's loading the game.

Now when I use "a"to start the game (open game) I get a black screen and that's it...it won't load any further (believe me, I've waited 15 minutes)
When I use "start" to start the game (open demo) I get a black screen, followed by a white screen...and this too, won't load any further (again, not even after waiting 15 minutes...)


I did everything I could find on the internet regarding this game, namely:

Using Gameware version 36a
Firmware version 35 (normal one, not a bèta in another language)

I've written my rom (the venom one) with "trim rom", "4x DMA" and "software reset"
According to m3wiki.com, these are the correct settings for this game...

I use an M3 SD card, with a sandisk 2gb SD card.
I have an "old/regular" nintendo DS
I never had any trouble playing other games (last game I playes was Zelda; phantom hourglass)

my m3 card looks like this:

my passkey2 looks like this:

And this is what my SD card looks like:

I'm 100% sure I have the right Rom, because it works with most of the people here.

Sorry for any grammar/spelling errors...I'm Dutch, not English...

Please help me

 

sorry for double post...

I already checked the stickies, and the only thing I could find about white screens is regarding the GBA, not the NDS...also, I've had white screens back when I just had the M3, and that was because I didn't "write the game" with gamemanager...I write games with gamemanager eversince and never had any problems...
also, I'm 100% sure I did just like the m3wiki said...and that has always worked for me.
