Visualize crashes every time when i try to import MDL appearance

Hello,

when I try drag-drop MDL appearance from exporer window to model - nothing changes.

When I import MDLfrom appearance  from pallette - a message window appears (see attachet pic).

Also, I copied the message from the clipboard

When I quit the message window - visualize crash...

Last week I successfully used MDL materials without any problems.

Maybe something needs to change the settings?
