Move character access denied. Need help please.

[Lonely_Ghost]

Greetings.

Got such problem here: After typing movechar command, then char's name and code, automated mesage says that access for moving char is denied.
I don't think, that it's server's problem, because, it that case, there would be a plenty of such topics, and ship market would be dumped.

So, does anyone know, what could cause such problem? Wrong code, or anything else?
