File corrupted.

I tried to force check the file, but I'm still getting the same error. Please any helps?
Also is it ok to run the game without the retail launcher?

 

The error message box should indicate retail or gamez on the top of said window, indicating which one needs repaired. if repairing does not work, reinstall is most likely required. Yes, you need retail bdo for gamez to run. if you do not have it, the launcher will download it for you, or you can get it at http://forum.gameznetwork.com/threads/download-mirrors-client-v855-community-provided.210022/ (the 30gb file)

 

I'll try it. thanks you
