Regarding minecraft launcher

Hi!

I´ve been having problems with accessing my minecraft accounts. When I login through the minecraft launcher it says "Invalid password" even when its the right one. I have tried the following.

1. Change the password
2. Redownloading the game
3. Let my friend access my account and he did without any problems, so its nothing wrong with the accounts.
4. Redownloading Java to the latest version and clean my computer fully.

 

There is still an issue that I cant access the launcher or login to "Minecraft.net" I am able to login to Mojang, but not launcher or minecraft.net on my computer.
