Starting error

[Ricsikeasd]

So,the game starts up just fine,but after that a little mirror shows up with this:

Data.myp:
System.Exception: You need to stop application currently using the following file: data.myp
a következő helyen: MYPHandler.MYPHandler.WriteFileToArchive(FileInArchive archFile, MemoryStream MS)
a következő helyen: MYPHandler.MYPHandler.ReplaceFile(FileInArchive archFile, FileStream newFile)
a következő helyen: RoRLauncher.Client.UpdateWarData()

Try moving the game folder else where and perform a reboot on your computer.
