Error on Deriv Trading (Dtrader)

Hi.
I have a problem in Deriv boom/crash that when i want to trade the error " Purchase Error: No further trading is allowed on this contract type for the current trading session" appears.
How can I solve that and what is the problem?

Thank you for taking this into consideration.

Também estou com esse problema! E pelo visto não há quem possa resolver, pois estiver a verificar essa resposta na comunidade eu não a encontrei. Ou ainda quem pudesse solucionar esse problema.
Fica muito difícil trabalhar assim.
