One other thing you can try is edit the registry key.
Before doing this from the help menu choose Backup/Restore and create the backup just in case things go wrong then you can easily recover to your present state.
Before opening the registry be sure to close Hoster first as it wont work properly if Hoster is running.
Now right click on the windows start icon and select Run, in the box type regedit.exe then OK. or you can type the same thing in the search box.
Once in the registry expand the HKEY_CURRENT_USER key, next expand the SOFTWARE key then again with the Micro Technology Unlimited key then Hoster lastly select Default and the window on the right will fill with all the Hoster saved settings.
Now look down the list for SingerSongsPosition, right click on it and from the drop down select delete.
Close the registry then start Hoster and see if the window now appears.

I attach a screen shot of the registry key to delete.
