The reason why the error has been generated is because there is already an existing value of 398-1048568 for the column ID in which you define it as PRIMARY KEY (values are unique) in the table you are inserting.
Do you have any Problems with ERA? If not, just ignore it? If u want to solve the issue, Open the Database, check the Entry and maybe delete it.
!!!BUT! Please Care, if u delete the wrong Entry, ERA will not work anymore!!!!
