Hi UE 4 Supporters,
Everyday I work well with UE4 but yesterday (Aug 6) I click on launcher.exe it updated something. After that I could not sign in UE4 (See the attached image).
I tried many times to uninstall/install but still got the same problem. If I tried wrong password it alerted immediately said wrong credentials.
Now I can not do anything with my unfinished work.
Help me pls,
