If you run into an error where the launcher is getting "stuck" on downloading a file, try the following.
Open up "c:\swgresurrection\tre" - delete all files that begin with "resurrection_"
Re-start launcher. Click update (or it will auto update)
If it does not finish, and say Client Read, run the SWG Resurrection uninstaller. Then, completely delete the directory "c:\swgresurrection"
Download the latest installer for the launcher and re-install the client.
