forge scala-lang xml error

[Icarus_00_]

Hi,

I tried installing minecraft forge 1.7.10 yesterday, but it didn't work, the installer window wouldn't even show up. After some research online, a saw a lot of people saying that i should try other versions, which didn't work either.
Finally i saw a comment that actually seemed to work, it told me to instal using the cmd [java -jar forge-1.7.10-10.13.4.1614-1.7.10-installer.jar], which did work, but after a few seconds the installation stopped and a window showed up saying that there was an error saying that some libraries failed to download, more specifically, org.scala-lang, and there were multiple libraries like that one missing. Someone told me that i should download directly the libraries and place them in the correspondent files inside of  "C:\Users\Utilizador\AppData\Roaming\.minecraft\libraries\org\scala-lang", amazingly these seemed to work, but there is one library that even though i have it in the correct place, and it's on the correct version, it doesn't work, i've tried to download it multiple times, and even tried different versions, but nothing seems to work.

- this is the version i have in C:\Users\Utilizador\AppData\Roaming\.minecraft\libraries\org\scala-lang\scala-xml_2.11\1.0.2

And now i can't even use any of my other minecraft versions, Is there a solution that anyone knows of?

I'll also leave this here, in case it helps at all...

Spoiler
