Database Question/s

[gbstn10]

I am trying to display a single category of a database in a custom HTML page (in Pages), but it doesn't seem to work. I know I need to use {database="1"} to display the database, but {database="1" category="1"} doesn't display the category. I get an error saying that I either cannot have two databases in the same page or that the database is already in use on another page (I use 'database 1' for my blog front page).

Is there a way for me to display a specific database category on a custom page?
Is there a way to deactivate the 'number of databases on a page' restriction so I can override the warning and save the page with more than one database?
