After updating to build 730 today, the program randomly crashes on startup. It will run if I open it again, but the Strategy Tester will not work.

Here is the information from the terminal crash:

Problem signature:
  Problem Event Name:    BEX64

If I attempt to start it again, it will run. Here are the entries in the Journal after startup:

GN    0    Terminal    21:24:18    MetaTrader 5 x64 build 730 started (MetaQuotes Software Corp.)
OH    0    Terminal    21:24:19    OpenCL initialization skipped due to critical error. Please update video drivers.
JK    2    Terminal    21:24:19    OpenCL will be initialized during terminal's next launch.

By the way, I am running the latest video drivers for my card.

When I attempt to run the Strategy Tester, I get the message "MetaTrader 5 Strategy Tester Agent has stopped working". The Tester Journal shows "tester agent authorization error". Note that I am not using remote agents. Here is the crash log from the tester agent:

I have tried uninstalling and reinstalling MetaTrader 5, updating my video card drivers, as well as rebooting my computer. Nothing works.

By the way, I am finishing up a book on MQL5, and this really throws a wrench in things.

Okay, so this was fixed quickly. I am using an AMD video card, and was experiencing a problem with another unrelated app crashing on Windows login (kdbsync.exe). The problem and solution are detailed here:

I had to uninstall the "AMD APP SDK Runtime" using the AMD Catalyst Install Manager. After applying the fix, the MetaTrader crashes were fixed as well. It appears the problem is related to OpenCL and some software installed with the latest AMD drivers.

Kdbsync.exe has stopped working?
