Launcher Error "Unspecified Error"

@MmoBiz

See if this guide link helps first

try this :

- close the launcher

- go to task manager and end task on all bitraider processes

- go to your swtor game installation directory, delete Bitraider folder.

- run the launcher, check if the repair option is available. use it if available.

it is often Bitraider the problem.

UPDATE: After trying both of the suggestions, it is now stuck with "ST Initializing" on the bottom. I have left it alone for a couple of hours and it does not update.

After the last downtime 06/26/2017

I log into the launcher, has initializing next to the ST letters bottom left
then after a while text appears saying "this application has encountered an unspecified error. please try again."
have tried this approx. ten times with same result
downloaded and reinstalled game client (more to reset to defaults)
then had old launcher with still the same error
ran file LauncherRepairUtilityP1.8.2.exe
this returned the newer launcher however the error remains.
I have also noted that a bitraider Icon appears on my task bar with the following message that says "unable to communicate with external UI. Exiting..."
have tried turning off all AV/Firewalls
confirmed Swtor is allowed through the firewall
placed bitraider on the approved list for the firewall.
still the error continues.
All other games played through the network from this computer and other computers work well. Only stopped after the downtime was working fine before hand, and Yes I know it was only a back end maintenance and should not have effected clients.

thanks in advance for any help

If the troubleshooting steps have not worked so far, you can try @proxos666's guide on converting from Streaming to Non-streaming here. Heed the warnings though, only try it if all other troubleshooting has failed, as it involves re-downloading the game.

this just now happened to me and I followed everything and it worked thank you so much
