If you also get unspecified error see this guide link
Is handy to know what antivirus is being used, some can interfere.
ESET - disable "protocol filtering"
Kaperskey - disable "scan secure/encrypted connections"
Norton (Firewall) - set exceptions to "Allow" not "Auto"
If using AVG ensure bitraider mini support service stub loader is removed from the "put to sleep unless activated" list in the AVG maintenance
There is a few options to look at
1. ensure launcher.exe , swtor.exe and brwc.exe are in all the exception lists for the anti virus and firewall.
2. Run the game shortcut as administrator
3. if you find you absolutely cannot solve the initializing error consider switching to non streaming (link to guide) (involves a new game download initially)
Hope this helps
