Since today, the patching process in the starting interface everytime stopps between 70 and 80%. The "Recieved" numbers change, but not the "Patched". I have restarted the process and the program a few times, but everytime it stopps between 70 and 80% (mostly on 77/78%). what can I do?

UPDATE: I don't know why, but now the patching progress has finished....:/
