Return of Reckoning

I have posted the problem before but no actual solution was found.When I log in to my acc from the launcher I see the backround with the flags and the camp but soon after this message popps up: CRITICAL ERROR authentication - application will now terminate . The game closes. Ive been having this problem on my new pc (8.1)while I can play just fine in my old laptop. I try repeatedly logging in but after the same thing happens (the pop up) on some random try this appears " Data.myp:
System.Exception: You need to stop application currently using the following file: data.myp
σε MYPHandler.MYPHandler.WriteFileToArchive(FileInArchive archFile, MemoryStream MS)
σε MYPHandler.MYPHandler.ReplaceFile(FileInArchive archFile, FileStream newFile)
σε RoRLauncher.Client.UpdateWarData()
.I looked at previous post and they all say to remove write only from the folder. I go on my screen right click the warhammer folder (both ror launcher and WAR inside) and I remove write only, I press ok. Same trouble again (both pop ups) .But when I right click the folder again it shows that write protect isn't turned off,Not even if I do it many times on a row. Maybe that's the whole issue .I think user Feidam has been having the same problem.If so I would appreciated if he confermed what im saying. Pls guys im desperate. this is as detailed as I could possibly go.If any1 has any hints I would gladly hear em.Thank you.

thx elven ill try it now

I tried moving it to several locations still it didn't work. .If you find any solutions I would gladly hear em. thank you.

I have similar problem. After starting game I can see the character choosing backround with the flags and the camp but soon after this message popps up: CRITICAL ERROR authentication - application will now terminate.
I downloaded game twice - once using torrents and second time from MEGA. Same error.

Data.myp:
System.Management.ManagementException: Invalid class
at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode)
at System.Management.ManagementObjectCollection.ManagementObjectEnumerator.MoveNext()
at MYPHandler.MYPHandler..ctor(String filename, del_FileTableEventHandler eventHandler_FileTable, del_FileEventHandler eventHandler_Extraction, HashDictionary hashDic)
at RoRLauncher.Client.UpdateWarData()

Still no change.... Sigh starting to give up.
