I'm using shinigima launcher. Thank you for the quick reply btw.

So, here's my problem: I download forge 1.14.3, i open it and i click "Install client", it seems to install correctly but at the end it says this: "Failed to run proccesor: com.google.gson.JsonParceException:Error parsing arguments in version json. File is corrupt or its format has changed. See log for more details." I try to download it again but nothing, i can open it with rar but i don't know how to install it manually or if it is going to crash my minecraft, in versions i have a folder with the name of: "1.14.3-forge-27.0.51" and inside it's a json file named: "1.14.3-forge-27.0.51.json". Hope someone can help me with this problem, thanks.
