Fehler beim Antworten eines Tickets

[hrban]

Hallo,

ich verwende OTRS 3.3.6, Windows 2008R2, MSSQL und IIS.
Seit heute bekomme ich, wenn ich ein bestehendes offenes Ticket beantwort nach "Mail übermitteln"
folgende Fehlermeldung:

Backend ERROR: OTRS-CGI-10 Perl: 5.16.3 OS: MSWin32 Time: Tue Sep 9 12:59:09 2014 Message: Can't get ArticleID from INSERT!
RemoteAddress: 192.168.0.1 RequestURI: /otrs/index.pl Traceback (3936): Module: Kernel::System::Ticket::Article::ArticleCreate (OTRS 3.3.6) Line: 293 Module: Kernel::System::Ticket::Article::ArticleSend (OTRS 3.3.6) Line: 2069 Module: Kernel::Modules::AgentTicketCompose::Run (OTRS 3.3.6) Line: 784 Module: Kernel::System::Web::InterfaceAgent::Run (OTRS 3.3.6) Line: 871 Module: PerlEx::Precompiler::c_::otrs::otrs::bin::cgi2dbin::index_pl::__ANON__ (unknown version) Line: 41 Module: (eval) (unknown version) Line: 458 Module: PerlEx::Precompiler::Execute (unknown version) Line: 458

Was ist hier plötzlich das Problem?

Danke Chris
