One thing to do when you go to C:\Program Files (x86)\Electronic Arts\BioWare\Star Wars-The Old Republic delete any patch folders
back to the file in the bitraider folder, delete the swtor_swtor file and start the launcher and try the game again it should create a new log which wont be as large and should attach ok
Delete the entire bitraider folder , it will recreate on the next game launch
Here, did what you said and I am trying attaching the swtor_swtor file now.
It looks to be some sort of loop occuring , and is likely firewall related , i gather you have tried turning off any firewall on the router/modem as a test
Given the amount of time you have spent on this it is likely better to switch so this issue with bitraider is removed.
