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.
Reset the code again. It might be the fact that you ether type it in wrong on the new accounts end or you may have typed it in wrong on the characters end. Set it to something simple like 123
Capital and small letters also effect, check code and name carefully for large and small letters of code and name of ship look for commas and other things as well
You can ignore reality but you can not ignore consequences of ignoring reality
