array variable dimension range exceeded error

I'm fairly new to autoit and I'm having issues with reading from my array. My scripts is basically as follows:

$MyArray = IniReadSection ("Someini.ini" , "iniSection")
$NoElements = UBound($MyArray)
$i=1
For $i = 1 to $NoElements-1
MsgBox ($MB_SYSTEMMODAL, "", $MyArray[$i])
Next

The $NoElements variable returns the correct number of elements in the array (+1) however when I try to display the values in a message box I get the range exceeded error. I tested the _FileWriteFromArray after I created the array so I know its not empty.

Can someone point out where I'm going wrong.
