Amazon AMTU Software Project.

I have moved to a new server, the Amazon AMTU software which worked perfectly well, on my new server it keeps crashing after 5-10 minutes, I need a company that can have a look and see what is wrong and rectify it, at the moment when stock is sold on my site or Amazons it reduces levels at each, whe orders are shipped on our site it automatically sets the Amazon sites to shipped on new sever when orders are shipped on our site after a short while it sets the order to un-shipped, only someone who is familiar with this type of work should take the time to bid.
