My personal EAs won't run after metatrader update on more than one broker

I see that metatrader is now keeping track of purchased EAs, but now the EAs that I have written are not working. I keep getting an error 4112, which is " 4112 . ERR_TRADE_EXPERT_DISABLED_BY_SERVER. Automated trading by Expert Advisors/Scripts disabled by trade server." How do I get around this

Simple pip calculation

I've found this be a simple way to calculate pips without concern of digit variations between JPY and other pairs. Also, the spreads are taken into consideration for a more accurate view of how many pips you've actually earned. numberOfPips = OrderProfit() / LotSizes();
