Error with the launcher!

[Kripa]

After starting RoRLauncher getting this error:

Data.myp:
System.Management.ManagementException: Invalid class

в System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode)

в System.Management.ManagementObjectCollection.ManagementObjectEnumerator.MoveNext()

в MYPHandler.MYPHandler..ctor(String filename, del_FileTableEventHandler eventHandler_FileTable,
del_FileEventHandler eventHandler_Extraction, HashDictionary hashDic)

в RoRLauncher.Client.UpdateWarData()

Ive tried the lodctr/r thing, tried to re download the game, tried to uncheck the "Readonly" of the game folder(But it doesnt work), the WAR.exe isnt readonly, tried this:

Run "regedit.exe"
Navigate to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PerfProc\Performance"
Ensure if you have a DWORD entry named "Disable Performance Counters" that if it was set to 1, that it is properly set to 0 (zero).
ive downloaded World.myp from this forum, didnt work...if theres any cure pls give it to me, ive suffered enough!

UPD: Downloaded Data.myp from this topic: http://www.returnofreckoning.com/forum/ ... %3A#p85048
UPD2: Changed windows account security settings to the minimum and the game started, but the error remained(Window with a message) any way its working now.
