Room Finder - Choose an available room - Empty -outlook 2010

Hi,

I have been assigned to create these meetings room.

Have been doing this by following this method http://blogs.technet.com/b/exchange/archive/2010/04/14/3409791.aspx

http://blogs.technet.com/b/educloud/archive/2011/11/07/get-a-room-enable-room-finder-with-room-list-distribution-groups.aspx

but as in the room finder, i can see the group i created in the show room list, but in Choose available room it's empty.

I'm not running with cached mode. So what can i do to solve this issue.
