My assets disappear when I leave the Editor to write scripts

Hi everyone, I’m new to Unity and C# and I’m having trouble with a couple things actually.

One thing that may help me tremendously if I can figure it out, is whenever I leave the Unity editor and go into Monodevelop to write scripts, and then I come back to the Editor, my assets under the Project window all disappear. So my scenes, and scripts are all gone. If I want to bring them back I have to Right click on Assets then click Reimport every time before I can print something to the Console.

I’m thinking there has to be a better way. Something that keeps all my Assets there without me having to Reimport them every time? Is there a setting I need in order to keep my assets from disappearing?

I have trouble adding my scripts to the Game Object as well, and I wonder if that has anything to do with it. When I first create a game object, it won’t let me add the script I created under the Object. It always says “Can’t add Script, Can’t add component because it doesn’t exist. Check to see if the file name and class name match” They do match so I’m not sure if this is all somehow related?

Thank you in advance for any help. I’m really looking forward to building alot of fun games with Unity, but these issues I’m having have been very discouraging. I appreciate any help.

Does this happen on a new project also? What OS, and what version of Unity are you using?
