MT4 BUILD 600 crashes w/ ea

 

I run several mt4 terminals with a digitrade EA ( for signal sending); since Build 600, any terminal running the ea crashes (even if I only run 1 terminal at a time), of course, that didnt happen with older buids.

Ive checked that the EA and its dll file are in the correct place, but for no avail. any help?

Reason:
