Assura 3.1.4 LVS error

Hello,

I'm facing a problem with assura 3.1.4 in the LVS. Independentely on the kind of circuit i run, the DRC works according to the design rules of my technology, while the LVS systematically fails with this error message (example of a simple inverter   http://postimage.org/image/e8qzr6zxr/ ):
