Thank you for your reply, egoddess,
My name is Shane Fletcher, Partner at Twilight Render.com
We respectfully request your site take action against this illegal distribution immediately. Twilight Render is very inexpensive and high quality. There is no reason to steal it. We made Twilight inexpensive so that it would be accessible to everyone.
Twilight Render has obviously been ILLEGALLY PIRATED AND REDISTRIBUTED ON YOUR SITE. This is both sad and shameful. If it were truly "For Educational Purposes" then Pisces would have contacted us and ASKED for permission to translate and redistribute. We were never asked nor contacted, though our contact information is easily available.
In addition, Pisces, or a partner, has "Re-branded" Twilight Render for this illegal distribution, changing the logo from yellow to green, and Illegally re-used a rendering WE PERSONALLY CREATED with Twilight.
%(#BF4000)[So they have stolen:
- Our Software, 1. our Logo, 1. our Images, and 1. our potential customers.
In addition, Pisces is apparently claiming copyright on something Pisces was never given permission to do, and obviously knows is illegal and wrong. We, again, respectfully request your site take action against this illegal distribution immediately.]
We are pleased with all the talented and creative Chinese users finding Twilight Render so easy and fun to use. 
Twilight Render is very OPEN AND WELCOMING to creating versions in different languages, and we are also committed to providing help for "educational" institutions... those interested need only to ASK and be given permission. We will gladly work with someone to translate the software, but rights will NOT be given to redistribute on any other website for pay or free. We are the only one with the right to distribute Twilight Render. Pisces clearly knows this.

Partner, Twilight Render
