Creating an account

[Milmod]

Hi
For some unknown reason the site I have built wont allow anyone to create an account or log in.

All that happens is that the page comes up Cannot be Found.

Has anyone else had this problem and if so can they let me know how they have corrected it?

I have checked the files and both files are there under Oscommerce/Admin, aswell as just in Oscommerce/

Im not sure if these are the right files or if they are in the right place though, so if anyone has a copy of each of the files can they send them to me so I maybe able to see if the files are correct.

Or any other advise is more than welcomed.

Thanks.

David
