[Plugin: Widget Logic Visual] Widgets disappeared

Using Widget Logic Visual 1.52 in WordPress 3.3.2
Set up widgets in Garland Theme with right and left sidebars
Everything worked great… no problems until a few days later…
Widgets in right sidebar dissappeared
Have checked on multiple computers using IE8 and latest version of Foxfire – results are the same
Widget Logic Visual says the widgets are in the right sidebar but they are not visible
Can add and delete widgets in the left sidebar without a problem
Love the plugin but need a little help…
