Newb: Installation error/issues

Hi,

I'm creating a website for a photographer and need to maximise the SEO as the site is largely image based, hence wanting to understand this module properly...

I'm using D7.20.

When I first installed the module, by ftp, I got the following error *before* activating it. It occurred when I clicked on the "Modules" link in the top menu:

PDOException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'sites/all/modules/schemaorg/schemaorg.module' for key 'PRIMARY': INSERT INTO {system} (filename, name, type, owner,

) in system_update_files_database() (line 2307 of /home/dotcamer/public_html/mysite.me.uk/modules/system/system.module).

When I saw the error I clicked the Back button in my browser, clicked the Modules menu again and was taken to the modules page without the error being seen again.

However...

I'm *not* seeing any reference to "Schema.org" at the bottom of my content types but I'm not clear if I should be or not... Neither do I see any reference to the module on my Configuration page but again, I'm not sure if I should be...

Did my install go wrong somehow?

Hope you can help :-)
