After it's installed, you need to stop polling, File->Configure Polling, then click "OK". That should download the new config file from the AH server, which tells GR3 that the SR data is available.
You get four tilts of SuperRes BR, BV, and CC. GR3 synthesizes SR SRV from SR BV. The products are included in the AH SSE system so you'll get the products as soon as they are generated on the server. Timing between SR BR and HR BR varies. Sometimes SR is a few seconds sooner and sometimes a few seconds later.
