historical issue with Metascore indicator

I am getting the dreaded “This trading system was stopped because the historical data loaded was insufficient to calculate at least one indicator during the evaluation of the last candlestick.”

I have a simple system using PRT Bands and a custom indicator I bought called Metascore. I have tried disabling everything and it seems Metascore is the issue. But I have used in before in other systems with no issue – can anyone see what is wrong? Thanks!
