This program shouldn't run at all. Check this:

int menu;	
[...]
while (menu != 9)

You're using the variable 'menu' without it being initialized. That could (and probably will) crash your program.
Change the initialization to give it a initial value: int menu=0; Another thing: the word 'or' isn't used in standard c++. Change it to || (two pipes)

Now for your original question "Why is this array not printing in 2D?"
If you look at your 'showArray' function, you can see that you use 2 nested loops correctly to loop through your 2d array. But you have to keep in mind that 2d-array's aren't stored as a big squares in the memory, that's just how we humans describe something 2d :) Think about it: How would it store a 5-d array? (they are legal to use in C++)

So you'll have to tell your program to jump to another line after each row is done. This can be done by adding one line to your function:

void showArray(int array[][COLS], int rows)
{
	for (int x = 0; x < rows; x++)
	{
		for (int y = 0; y < COLS; y++)
		{
			cout << setw(4)  << array[x][y];
		}
		cout << '\n'; // print a 'newline'
	}
}

You used defines in C++, most people look down on that for the reason that you can also use (static) const unsigned ints in your case. It has the benefit of type checking.

The array initialization is okay with the brackets, but if you make it a loop you won't have to update it manually each time. Maybe you can read up about memset().

The menu decision part now consists of if... if... It's more natural to make that a switch statement.

All of these tips won't have impact on the output of the program, but they are useful nonetheless.

Horribly off topic, what game is this? X in a row? Sudoku? The rest is looking good. :)
