SQL Error with Duplicate Entry Problem

[Kat8990]

Every time I do a test order and create a customer with a fake email I get some kind of duplicate error message like the following:

SQL Error: Duplicate entry '205106-1' for key 'PRIMARY'
Error No: 1062
SQL: INSERT INTO abwk_order_data (`order_id`, `type_id`, `data`, `date_added`) VALUES (205106, 1, 'a:2:{s:3:\"uri\";s:16:\"glogan@email address\";s:6:\"status\";s:1:\"1\";}', NOW() ) in home/smallbu4/public_html/WEBSITE NAME/core-database-amysqli.php on line 106   

The error message is telling me about a problem in the amysqli.php file. How do I fix this problem?
