Hello James,
We don’t set limitations on the usage of our EAs – you can use them on any kind of account and on as many accounts as you like.
This sounds like some protections being hit but to help you better I would need some screenshots from the MetaTrader platform and some more details about your account size and the actual EAs you trade.
I requested them via email, please reply in the thread so I can look into this and tell you what’s happening.
