Widget not supported, entire site is based on it !

Just tried to import my widgets, MOST are a list link that is basis of my MENUS -but the message is, over and over and over, widget not supported !!!!!

Is this a glitch, if not, can it be fixed? If it can't be fixed, please delete the site. Thanks anyway.
I'm not going to rebuild it from scratch for a widget that isn't "supported!.

That's the problem, print-screen right there.

Most of my web site is constructed with these lists as menus - goodbye.jpg

There's no widget called list by default in WordPress, I guess you used a plugin. If that's right you just need to install that same plugin.
