Problem with adding widgets in Mystique theme

hi everyone
i have a probleme when i add wdgets in the default sidebar in mystique theme,i’m using a free web hosting haven’t buy a server yet but,when i add widgets in the default sidebar which has already 4 widgets came with the theme, they just desappear and all i can see is the one that i added!!!
here’s a exemple before i add a widget https://maxmp3.eb2a.com/wp-content/uploads/2011/06/no-widget.png
