Assets/ServerAndClient/Server/MySQL/SQL_PasswordRecovery.cs(8,18): error CS0234: The type or namespace name `Mail' does not exist in the namespace `System.Net'. Are you missing an assembly reference?

 

Which platform is your project set to? System.Net is only accessible in PC/Mac builds.

 

I'm not sure... how to check and set it up?

 

Under the File menu you will find the Build Settings, the platform the project is currently set to will be highlighted
http://docs.unity3d.com/Manual/BuildSettings.html

 

why it said no PC, Mac & Linux Standalone Module Loaded?.... when i click open download page, it said...

is this asset only for web player?

 

You'll have to reinstall Unity with "Windows Build Support" checked at the Choose Components screen. Right now it seems like you don't have it installed.

 

im sorry my mistakes, UnitySetup-Windows-Support-for-Editor-5.3.4f1 should be install first, thanks for the answer jhony 10
