Return of Reckoning

[Written to the translator (I'm FR)] Hello, last night I downloaded the game and when I run I get a menu offering me the option, credits, kinematics, etc .... and also a small black rectangle on the right is empty. So I searched for answers to this problem and I found. I replaced the file present with the files from the links you give mlais it does not matter. Another thing: When I start the game rectangle ERROR launches and contains this : Data.myp:
System.InvalidOperationException: Can not load the counter name data because Invalid Index '' was read from the registry.
   to System.Diagnostics.PerformanceCounterLib.GetStringTable (Boolean isHelp)
   to System.Diagnostics.PerformanceCounterLib.get_NameTable ()
   to System.Diagnostics.PerformanceCounterLib.get_CategoryTable ()
   to System.Diagnostics.PerformanceCounterLib.CounterExists (String category, String counter, Boolean & categoryExists)
   to System.Diagnostics.PerformanceCounterLib.CounterExists (String Machine, String category, String counter)
   to System.Diagnostics.PerformanceCounter.InitializeImpl ()
   to System.Diagnostics.PerformanceCounter..ctor (String categoryName, CounterName String, String instanceName, Boolean readOnly)
   to System.Diagnostics.PerformanceCounter..ctor (String categoryName, CounterName String, String instanceName)
   to MYPHandler.MYPHandler..ctor (String filename, del_FileTableEventHandler eventHandler_FileTable, del_FileEventHandler eventHandler_Extraction, HashDictionary hashDic)
   to RoRLauncher.Client.UpdateWarData ()

Can you help me ? Thank you !
