Star Wars The Old Republic - Stuck on login screen

@Music4UHD

Start with the basics and ensure launcher.exe and swtor.exe are in all the exception lists for the antivirus and firewall

I have my firewall turned off so i dont think that would be a problem

Are you using Zone Alarm or AVG?  Try running the launcher repair utility here

You can also try a normal repair:

Non-Streaming launcher - Log into the launcher but don't click Play. Check for small letters "ST" in the bottom left corner. If this is NOT present, With the new launcher after login , select the username pull down on the top right and select settings, then press repair.

Streaming launcher - If the letters "ST" is present, close the launcher, right mouse click on the game shortcut, select open file location and delete the BitRaider folder. Then start the launcher.
