Also you have send me only llah.dll in that .rar archive. I wanted to get llahlog.dat file instead. This way I will know exact settings for your computer and processes list. Sometimes muerror.log doesn't fetch all the information correctly.
Can't say for sure because i'm not infront of your PC, but problem might be any (caused by hardware, bios settings misconfigured/altered, Operating System issues or just some antivirus conflicts). For now you can try reinstalling all antiviruses and install new one, I recommend AVG free or NOD32 (paid, trial would work too for now) (have just one, but not few installed software for antivirus). Make sure that antivirus doesn't block the client and no files is missing or re-downloaded every time when you run the game via AutoUpdate.EXE from your client root folder (auto updater tool).
Thanks
