Trying to record a demo in 'Korax Arena' I've got following:

Dev: Server spawned
Dev: CL_EstablishConnection: connected to local
Dev: Client LOCAL connected
- VStream::SerialiseLittleEndian
- CL_WriteDemoMessage
- VDemoRecordingNetConnection::GetRawPacket
- VNetConnection::GetMessages
- CL_ReadFromServer
- Host_Frame

ERROR: Segmentation Violation

What may be a reason of this problem?

Fixed.
