Thanks. That's a crash in a DLL process, not in the script or in the Zorro process. So I suspect that one of the new FXCM DLLs is not compatible with one of the modules or background processes on your Win32 machine. If it happened exactly at 23:00, it could have been triggered by a server event at that time.

You can try to fix it by reinstalling a fresh Windows version on that machine, maybe 64 bit instead of 32 bit. Otherwise do not continue FXCM trading on that PC.
