MT5 EA Problems

 
Hey, I have used this EA since half a year. Then ive downloaded a the latest version of MT5 Windows from the official website and applied the EA to it.
It has strange problems with Arrays.
Im storing all Positions in a Array and use it to manage my positions.
The EA can open Positions but the positions aren't added to the array. (that's my speculation at the moment without further testing)
Because its working on old versions of MT5 but not on new.

Has anything changed I need to know or are there some issues with MT5?
Thanks for Help
