Opennest error

We have a few grasshopper procedures which have stopped working with the openness component reporting the following error. Any ideas on whats happened?

  1. Solution exception:Could not load type ‘DeepNestLib.NestingContext’ from assembly ‘OpenNestLib, Version=, Culture=neutral, PublicKeyToken=null’.

any chance of some help with the above error would be greatly appreciated.

I think you are using an old version of OpenNest.

Delete and try to install it from Rhino PackageManager version 1.5.1

Thank you Petras for your reply, I’m sure that will be the fix I need
