Cinnamon failed: desktop only, no panel, no dialog frame

view story

http://unix.stackexchange.com – [moved in from ASK UBUNTU] I am using Linux Mint 14 (MATE) with Cinnamon installed. Cinnamon failed when I tried to delete an item on the menu with menu editor. The system freezed, so I logged out by pressing ctrl+alt+del. When I logged back in, the desktop panel was not loaded (shortcuts were there as normal, right click works as well). I can barely do anyting but get the terminal with ctrl+alt+t. But all the dialogue windows are presented without any frames. Here are the screenshots (I have no enough reputation to post image here, sorry): http://i48.tinypic.com/345orvs.png and http:/ (HowTos)
