Ngui purchase not working

[Pratik Parikh]

Hi ,
  I had purchased ngui today version 3.8.0 in which I had got a ngui paid folder it seems there is a unity project
inside this folder ,in which there is a ngui folder which has Upgrade Tools (2.7.0 to 3.X) package. If i import this package there is a error . So how can I import the new version of Ngui inside my existing project in which i am using ngui free version 2.7.0.?

 I was expecting a ngui.package file so that I would have created the new scene and deleted the existing Ngui folder and would have Imported the new package.

 Is it that I had made a wrong purchase?

Well, first, there is no 3.8.0. The latest is 3.5.8. Next, where did you buy it? Standard liceses from both tasharen.com and the Unity Asset Store come as Unity packages. I you get a Professional license then you get access to the github, which contains the entire project.

Ya sorry it is version 3.5.8 i downloaded NGUI Next-Gen UI.package but when i delete the NGUI 2.7.0 after creating the new scene & then i import the new package everything is turning to pink. For Atlas shader it is showing No shader & when i am trying to create new atlas, It is not getting created in my existing project. but when i am trying to import the package in new project & create atlas everything works fine. So how can i upgrade my existing project to new Ngui version 3.5.8 so that my work doesn't get affected ?

Did you copy files from one project to another at any point? If you copy files outside of Unity without the associated metadata, all Unity's links are completely broken, and it becomes incompatible with the project you copied the files from.

I am using svn so i reverted my ngui part to 2.7.0 and its working fine for me. But when i am importing the ngui 3.5.8 package then it is giving problem , The atlas material which are already created in 2.7.0 show there is no shader , when i am trying to apply the shader unlit/transparent coloured i am not getting the option in drop down of shader so i  need to apply unlit/transparent. Its not creating the new atlas too. But when i am importing the package in the new project its work fine & it apply shader to the atlas material to unlit/transparent coloured.

when i am trying to apply the shader unlit/transparent coloured i am not getting the option in drop down of shader

Why not? Where is the shader located? Do you see errors in the console log?
