Having the same issue. Tried to launch several times tonight. First couple of times it downloaded some files quickly then went to another download screen that was frozen at Downloading 0 (0). Would close that screen but client stuck, can’t shut it down with task manager. Now I only get the Downloading 0 (0) screen and can’t end client w/o rebooting pc. Tried renaming .dat file to .old and restarting – no success. Tried adding “-repair” to the end of the target line – no success. Looking for some help.
