unknow order and error messsage pop up for these orders

[MoreYummy]

I have live license, but using sim101.

Once a while there is a messages come up :" no permission to enter order", it may not be exactly like that, but you get the idea.
And then i checked the order Tab, there are some orders and of course they are all rejected.

I didnt place these orders, so can you find out what they are, and coming from?

I dont have strategy running either.

Just another one comes up.
i copied this 1 message this time.
" Account write permission denied Affected Order: Buy 1 Market"

"Ok" clickable.

I didnt enter anything, im just watching a demo account, even i have live license.

Hello MoreYummy,

This indicates that someone, using the same Dorman 'DoNotUse' account, is submitting orders to this account. Unfortunately the rejection error will appear in NinjaTrader for all Zen-Fire users that share this Dorman 'DoNotUse' account.

You can disregard these errors, it will not affect NinjaTrader in any other way.

The users that submits the orders will receive error message that will state not to submit orders to this account.

Please let me know if I may be of further assistance.
