Problems with my account and checkout process

[dean023]

hi can Anyone help as i'm a bit at a loss

 

when ever I click on My Account or Checkout I get the following:

 

 

The requested URL /oscommerce/account.php was not found on this server.

 

&

 

The requested URL /oscommerce/checkout_shipping.php was not found on this server.

 

I'm not aware that I've done anything to either and I reinstalled from a backup but nothing works

 

any ideas?

Thanks in advance
