Reinstalling Zorro normally won't help when something does not work. When you get different results, compare the logs. Then you'll normally quickly see the reason.

I suspect several reasons. First, you did not train the system. Since a portfolio strategy has different parameter files than a single-asset strategy, you must train it again when you made such a modification. Second, you did not trade with payout. The "AssetsFix" file is set up for normal trading with spread and commmission, so you must alter asset parameters for binary trading when you explicitly load it. And select the asset before modifying them, like this:

while (asset(loop("EUR/USD")))
{
...
WinPayout = 75;
LossPayout = 0;
Spread = Commission = 0;
...

I don't know if this is the whole problem, but anyway if this does not help, please post again and I'll look into it.
