Which version are you running ?
only I just tested what you describe on mine and restarting Hoster or rebooting computer does retain singers in rotation order.

It sounds like yours is refreshing rotation list on a restart.

When you installed Hoster did you use default locations ?
Do you save your playlists to the Hoster Data Folder ?
Do you set the Save AS for Playlist to another location?

When you have rotation set Hoster creates a file in the Data folder. Default location: C:/ProgramData/mtu.com/Hoster
With a .rox extension which is the rotation at time of closing along with .hst file of same name which is the whole playlist.

Open your Hoster data folder which you should be able to access from Tools menu/Hoster Data Folder then check the Path in the brows window, take note of the existing path then press the view button. If you save your playlist to the Hoster datafolder you should see two files of same name except the extension example name: United Services.hst & United Services.rox.
If you save your playlist to somewhere other than the Data Folder check that that it contains both files.

Take note of the .rox file size, if it shows as 1 KB then that is an empty rotation list, it shows greater as the rotation grows.

Answer the questions above and let us know your findings.

Regards Hoster crashing, is this a very frequent occurrence on your system ?
