I entered the portal for the Black Talon Flashpoint, and upon entering, my entire user interface had disappeared (all action bars, top menu, minimap, everything).
I was told that things like ctrl+u or alt+z would work, but it fails in completely restoring my user interface.
I was unable to communicate with my group and was forced to leave after only being able to attack with my general rage-builder.
Is there a fix to all of this, because this is really irritating. I've tried to find the local appdata in an attempt to wipe the user interface and start over, as stated below, but there was no app data for me to access, nor a SWTOR folder.
Ive had this a few times if u completely exit the game client close it all down in processors and then relaunch and login again it should be back. I wouldnt delete your UI file tho
