Black screen after launching

[DigitalWurm]

Are you using a Mac?

Sorry, I forgot to mention I was using Windows 7, and i've updated java as well

 

[Scaffolding]

Are you running the latest launcher?
If so is it .EXE or .JAR file type?

.EXE

 

[Scaffolding]

Can you try using the Jar instead otherwise the only things I can suggest are:

1) Try running the EXE in compatibility mode or run as Admin
2) Update lwjgl

Does C:\Users\Acer\Downloads\FTBLite\minecraft\bin\natives\lwjgl.dll exist?
