Hey - sorry to hear you're still having issues.
Have you tried clearing and redownloading your cache? It may or may not help, but we're seeing lesser volumes on the log-in servers now than earlier on today and it may be smoother now.
EDIT: made a thread to centralise discussion and find out what specific issues players are experiencing. Please head there and let us know your information and we'll try to help!
