Hi Rafi,

I found yesterday some (but not all) components had issues with GHv.0.8.0002 and 3, so I uploaded new builds of most today (If I've not uploaded one you need, let me know, the rest will be tomorrow).

I've also changed the location the plugins are loaded from (normally an issue for Windows64 bit users). If you already have todays versions and still have problems, please send me an email with a description of the error and I'll help resolve it.

Hello Jon,
I have the problem that all components SSI are deactivated and redly.
Possibly does not function your components on the Neusten Grasshopper version yet or the Licenz file does not.
Do you have an idea?
