Package manager failure

Hello. Installed Kangaroo .099, and have Kangaroo 2. But I am still missing the ‘SpringFromLine’ command, It is in none of the .zip files, and didn’t come in the initial UserObjects file from the Rhino install.

Can someone help me. Or provide me with the file for this command?

And also the Package Manager fails to download stuff, saying “Not all plug-ins were found on the package server.”

Please help, just trying to follow some neat tutorials and do shit on here, but falling down stupid and ((I’m sure (At least I hope I am sure)) shallow holes.

Thank you!
