help getting Arduino OBD-II Logger Kit #2 to run

Hi

I just received my
Arduino OBD-II Logger Kit #2
Unfortunately, there is no real documentation for it, so I tried finding the way to go by myself ;)

Up to now, I stacked the "Data Logger Shield for Arduino" on top of the "Compact MEGA 2560"and the "2.8? TFT LCD shield for Arduino" on top of that pack. For me, that's the only way it could work, but maybe I already made a mistake there?
Then I tried to upload Mgealogger example onto the Compact Mega but with no success.
Adruino IDE gives me some errors, Codeblocks gives me also warning.
So I decided to try the example from https://github.com/stanleyhuangyc/MultiLCD/blob/master/README.md

[code]
#include <Wire.h>
#include <MultiLCD.h>

LCD_SSD1306 lcd; /* for SSD1306 OLED module */

(I changed LCD_SSD1306 lcd; to LCD_ILI9325D lcd; to fit my equipment)

First error (of course...) is that SPI was not declared. So i added #include <SPI.h> and got rid of that.
Next error was

[/code]

So 54 warnings is a lot...
I tried and uploaded the sketch anyways but nothing happened. Shouldn't the lcd turn on, at least?

So I decided to use another, more simple example:
[code]
#include <Arduino.h>
#include <Wire.h>
#include <MultiLCD.h>
#include <SPI.h>

LCD_ILI9325D lcd;


void setup()
{
lcd.begin();
lcd.clear();

lcd.setCursor(0, 0);
lcd.print("Hello, world!");

lcd.setCursor(0, 1);
lcd.printLong(1234567890, FONT_SIZE_SMALL);

lcd.setCursor(0, 2);
lcd.printLong(1234567890, FONT_SIZE_MEDIUM);

lcd.setCursor(0, 3);
lcd.printLong(12345678, FONT_SIZE_LARGE);
}

void loop()
{
}
[/code]
(Already included SPI.h because it was missing as well...)

But again lots of warning:

[/code]

I also tried to upload that sketch without any success, the LCD stays dark.

So I would appretiate any kind of help to get at least something running.
Up to now, I'm not even sure the LCD isn't broken.
I tried the blink example and one LED on the DataLogger Shield is blinking, so that looks ok.

I'm running Win7 Pro 64, Codeblocks 12.11.

Thanks in advance!
