Return of Reckoning

I was fighting in central flag in prag, sudenly the game frozen and was completely stoped, so force reset it closing it.
Now after open the return of reckoning launcher, don't let me join and automaticaly appear this error, any idea what happened?

Please close WAR.exe
System.ComponentModel.Win32Exception (0x80004005): Acceso denegado
en System.Diagnostics.ProcessManager.OpenProcess(Int32 processId, Int32 access, Boolean throwIfExited)
en System.Diagnostics.Process.GetProcessHandle(Int32 access, Boolean throwIfExited)
en System.Diagnostics.Process.Kill()
en RoRLauncher.MainWindow.KillProcessByName(String program, Boolean two)

Can close the post, restarted the PC and now the launcher is working, no idea what was the problem.

Solved~
