UE4Editor-[projectname].dll missing

I am on Win7 using ue4 4.7.6

"The following modules are missing or built with a different engine version:

UE4Editor-TWUv0.dll

would you like to rebuild them now?"
If I click yes then.
“TWUv0 could not be compiled. Try rebuilding from source manually.”

Except I have done everything in BluePrints only. I have been working on this project on and off for a few months now and I am incredibly upset to see this error that renders me unable to load my game in the ue4 editor. I went to the .uproject and tried to generate visual studio project files but that seemed to have done nothing. I then attempting to downgrade it from 4.7.6 to 4.6.1 and that seemed to have work until I go to open it where I recieve the same problems and in the process of downgrading it generateed a .sln and a .suo file.

I right click on my .uproject again and try to change the version back to 4.7 but I get

“Running C:/Program Files/Unreal Engine/4.7/Engine/Binaries/DotNET/UnrealBuildTool.exe -projectfiles -project=“C:/Users/asdf/GD_TWU/TWUv0 4.7/TWUv0.uproject” -game -rocket -progress

Please any assistance would be greatly appreciated. I would really rather not have to scrap this :confused:

I have already gone to the folder and changed the property off of read only so I know that, that is not the issue.

I just made a new project and copied all of the files into it.

Hello, how do you do it? The new project with the same name?
