Hi Robert,
The main problem is most probably: Upload not allowed. Solution is developed for customer 2005.
I had a look but I cannot find what this means. Does customer 2005 have a meaning to you? The log files of the problem will have to be gone through. If this problem has not yet been solved, I would suggest that you create a ticket and development may have a look at the issue.
I hope I could be of assistance.
Kind regards,
Douglas Kisinger Thompson
