Hi Jon, The last license you gave to me now is working...,

I'll try it first.

Thanks for your help

Comment by Perwiro on January 17, 2012 at 7:50am

Ok, I've just checked up my license with the link u gave me and send it back to you.

I'll wait for your suggestion or new license then.

Thanks for your help.

Hi Perwiro,

I've just sent an email with a link for a diagnostic so I can advise about the license.

As for the GH crash, Rhino v5 (and Grasshopper) are still Beta, to my mind it's important to give developers like David a free hand to make improvements at this early stage for the best possible "mature" product.

I'm happy to help you (and others) as much as I can in resolving any issues that arise.  

Cheers,  Jon

Hi Jon..,

First time I saw the tutorial and what could be done by StructDrawRhino, I was amazed.

But still, up to now I can't try it yet, the first license you gave to me actually work, but when I install the Latest Grasshopper, my Rhino crash with GH, then after several time finding the solution, I found that it need to install Visual C++ 2005, then I install it and it works...

But, suddently my license's broke. Then I ask you for the other one, I have updated my license with the new one you gave me, but it didn't work

Could you help me out?
 I use Rhino SR 9 and Grasshopper 0.8.0065
