Have you recently installed or updated any drivers? From what I've found, that seems to be a somewhat common cause of ntdll.dll errors. EDIT: You might also post your problem in the CTD forum. The people there will probably have a little experience with it.http://forum.avsim.net/forum/262-crash-to-desktop-ctd-forum/

No, it's happening since I fixed my DLL.XML. I don't know if this is important, but that's the only thing i've done.Thanks for advice, I'll try in CTD forum

Editing DLL.XML is very likely connected to your issue, but I wouldn't know what to do with it though except maybe double-check it for syntax/spelling & such.
