Error after Installation

[maetsches]

Hi,

 

I have installed oscommerce like it is described in the documentation.

 

If I want to log me in as administration I don`t get in and there is this error message:

 

1062 - Duplicate entry '1874f26143c10484ab1e827bcb662600' for key 1

 

insert into sessions values ('1874f26143c10484ab1e827bcb662600c9f5c112', '1205620462', 'language|s:6:\"german\";languages_id|s:1:\"2\";selected_box|s:13:\"configuration\";')

 

[TEP STOP]

 

Where is my error? I have only installed oscommerce and I have nothing changed.

 

Thanks.
