To open a document which is stored on a Royal Server, you first have to open a document where the Royal Server settings are stored. Whenever a new document is opened, Royal TSD/TSi checks for Royal Server objects and contacts those servers to get a list of the stored documents.
Then, the next time when you open a document, Royal TSD/TSi will ask you whether you want to open a document or load one from a Royal Server.
Populating the Royal Server document list may take a while, depending on the connection speed. So, if you don't see the option to open a Royal Server right away, wait a couple of seconds and try again.
