Issue with MC 15 std Sim, order not exec.

Hello,
iam using oanda data for gold. when i sim in standard mode, i cannot use adv as mc15 just crashes.
when the bar replay is occuring, buy or sell orders do not execute or work, i have zero idea what is going on, i have attacthed a screen record - hopefully someone can shed some light on this. i find the software excessively complicated then it needs to be most of the time.
i have made a screen record here is the link to view it...
