Return of Reckoning

I have been looking through the forums and seeing if anyone else has had this issue but I can't find it anywhere. Anyways I get the box that says AN ERROR OCCURED... and it says the following.
Data.myp:
System.IO.IOException: The process cannot access the file 'C:\Users\ashle\Desktop\Warhammer Online\data.myp' because it is being used by another process.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy, Boolean useLongPath, Boolean checkHost)
at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access)
at MYPHandler.MYPHandler..ctor(String filename, del_FileTableEventHandler eventHandler_FileTable, del_FileEventHandler eventHandler_Extraction, HashDictionary hashDic)
at RoRLauncher.Client.UpdateWarData()

Also something else I'm noticing is every time I open properties I shows that my folder is read only even though I change it.

Issue solved, that version of directX wasn't installed correctly, I had just downloaded the installer not actually installed it.
