Problem with viewing single post ( custom post type ) )

Hey!

I’ve problems with viewing full posts of a custom post type I created. The custom post type I created is called “media” which has custom field for uploading videos and photos. The videos and photos are being displayed in a lighbox when giving links are clicked. I can query the posts from this custom post type and display on my blog. There is nothing wrong with displaying them in the archive as well. However when I want to view the posts from this custom post type as a single post, I get the 404 error. I created a single-media.php file as well but it didn’t help.

Any idea on what could be generating this error? Thanks in advance.
