If you are trying to download an automated trading system, their rules have changed, they want the customer to learn how to use cTrader Algo, backtest and optimise cBots using a trial version before attempting to purchase the bot. This is actually better for the customer as they learn how to use the system before they purchase it.
I am sure after 14 days on a trial you will know if you want to buy it or not, does not make sense for them to let a customer use a bot for 14 days and then have another 14 days free if they request a refund, so they do not allow refunds if a customer has already tried the bot and decides to by it.
