@xTwan We told you to take screenshots and google how to do that if you don't know. So no, you've not been "trying everything" we told you. Create a usefull topic next time, we are not here to look for your problems in other topics.
@xTwan One way you definitely won't get help is by spamming the forum with topics asking the same question.
Replace your launcher with this one and try again http://cdn.plutonium.pw/updater/plutonium.exe.
If it still doesn't work post the filepath to your launcher and post your windows username.
