Windows 10 again...
What is crashing is probably mql.exe, the original compiler that is used by fxdreema.exe and is located under /Data. Try to replace it with mql.exe from these links http://forum.mql4.com/61609#922370

Hello,
I replaced mql.exe found in the following location: C:\Program Files (x86)\fxDreema\Data
The link for the mql.exe file can be found here: http://files.metaquotes.net/metaquotes. ... t5/mql.exe
That fixed the problem thank you.
