Did you do this ?
•Press the [Windows] Key + [R] at the same time.
•Copy the following in to the text box and press ok: %localappdata%\swtor\swtor\settings
•Open the client_settings.ini file and ensure the following are displayed within, or edit/add if so required:
•Fullscreen = false
•D3DFullScreen = false
•RefreshRate = 60
•Save and close the file.
Problem 1: No longer fullscreen (Come on, windowed just sucks)
Problem 2: Still crashes without error
