Listing Problem

I am unable to add items to the database. I just keep getting this error message:
A critical error has occured (77.44.107.200)
This error has been logged and will be dealt with asap.
This happens whether I click on the amazon links or try to add an item manually.

Thanks Tom. Working fine now
