This one reported back a 0kb size for the screenshots - does this spark any ideas?
Here is a screenshot... showing the logs: http://screencast.com/t/FFyEwtXovWb
Well, this one has me stumped. Some areas I'd explore to try narrowing it down are:
Are you overwriting a file (using the same 'ID' variable value)? Is so, is the file already open?
You need to create an account at mql5.com
From there, you can lodge an issue with the service desk.
Please let us know the outcome!
