Minecraft tekkit launcher problem

[Mosca]

Hi everyone
It is a few days that I try to start the game but I have the following problem.
I use the hackphoenix tekkit launcher and any username I enter tells me that the user or password is not valid ....
does anyone have the same problem?
how do i solve it?

Could, try this launcher?

 

Allows any usernames and you just have to enter it and click play offline
