Open the mql4 file as WHRoeder suggested, check the insides of start() function like I told you.

I found the start() function but there was nothing like ArrayResize(array_name, new_size) there.
 
Ok. Care to share the file with the rest of us? We don't see the future or read from cards and stuff like that, posting the code, would help us help you.
