Bug Can't respawn

Yesterday night (20/03/2017) I was grinding in the dark palace with some friends and my computer crashed. At the time I thought I would just log back in and get the stuff I lost (I was fighting an enemy when it happened, so my character died), but the neither the respawn nor the title screen buttons were working. Since it was already late, I went to bed and was going to try again the next day, but when I did, I was still dead and both buttons still weren't working. I restarted my computer and tried again but it still didn't work. Is this a bug or is the problem only on my computer? If it is a bug, can someone please fix this?
