Ok this is fixing it the additional slash, replace line 59-68 with this:

$messagearray[1][$i] = "http://www.amazon.de/exec/obidos/ASIN".$asin[0]."ref=nosim/" . $associate_id.'"]';
         			}
         			elseif(stristr($messagearray[1][$i],"[/url]"))
         			{
         				$messagearray[1][$i] = "http://www.amazon.de/exec/obidos/ASIN".$asin[0]."ref=nosim/" . $associate_id."[/url]";
         			}
         			else
         			{
         				$messagearray[1][$i] = "http://www.amazon.de/exec/obidos/ASIN".$asin[0]."ref=nosim/" . $associate_id;
         			}
