Nuendo (32bits) 6.5.40 crash while using patch list xml

I just bought the Yamaha MX49 synthetiser, an i download the patch list XML file from Yamaha.
All working well after i do import it on the Device Manager but when i close and re-open my session Nuendo crash.
It say A serious problem as occured etc etc…I can only quit.

Ok fixed issue by reseting preferences. :slight_smile:
