EA always stops on 14.april.2017! (ERROR?) Why?

 

In every Currency i which i have tried the ea suddenly jumps off without any errors in the journal. Ticks lack an hour (23 PM).  it even moves on writing the wanted file and says "File successfully created" though the file should be finished 2 years after.

edit: its in EVERY market

 

for all those ffacing the same issue in the future:

try reinstalling MT5 seemed to solve this problem.
