If you click the YOU tab and then the green button on the top left of the hud it should prompt you to load a web page, If you have your viewer set to load web links in the Secondlife Web Browser this could cause issues and you wont be able to download your spread sheets this way. So it is always best to Load URLS with a external Browser such as Firefox, Opera, Chrome, ext.

If you click the YOU tab on the hud and click the green button a pop up should appear top right corner for any viewers that use the 1.x code base and for any 2.x code based viewers it should pop up in the bottom right corner.

If you do not get the pop up the number one reason is because you have either muted the hud or yourself.
this will make it so the hud can not display popups for you.

In 1.x code based viewers its called the mute list
in 2.x code based viewers its called the blocked list

1.x

Choose View menu > Mute List.

2.x

Click the sidebar's People tab.
Or choose Communicate menu > My Friends.
Or right-click your avatar and choose My Friends.
Click the Nearby or My Friends tabs.
Near the bottom, click the gear icon to show more options and choose Show Blocked Residents & Objects.

So please check this list to make sure neither the HUD nor Your name is on this list. If one of them is just simply *UN MUTE* or *UN BLOCK* it and then the hud should work for you.

Some older viewers are not updated as new code and functions are added to SL so some of the older viewers may not be able to use the functions that is in the code of our hud, and in some cases will prevent the hud from working at all if the Viewer is to old. For these issues we can not help and you will need to update to a newer viewer to get your hud to work.
