Saving Comment causes fatal error

Whenever a user attempts to save a comment, it generates 2 errors in my error log (Comment and php) and the comment is not saved. I've searched google and here and find similar problems with Feeds and images but not comments and I'm not sure how to fix it.

Here's the error:
PDOException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'comment-202-0-0-und' for key 'PRIMARY': INSERT INTO {field_data_comment_body} (entity_type, entity_id, revision_id, bundle, delta, language, comment_body_value, comment_body_format) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5, :db_insert_placeholder_6, :db_insert_placeholder_7); Array ( [:db_insert_placeholder_0] => comment [:db_insert_placeholder_1] => 202 [:db_insert_placeholder_2] => 202 [:db_insert_placeholder_3] => comment_node_article [:db_insert_placeholder_4] => 0 [:db_insert_placeholder_5] => und [:db_insert_placeholder_6] => test comment [:db_insert_placeholder_7] => filtered_html ) in field_sql_storage_field_storage_write() (line 514 of /home/uvumfcom/public_html/jonhainphotography.com/modules/field/modules/field_sql_storage/field_sql_storage.module).

Any help is appreciated.
