Hi,

Last Beta version, was working OK.

Since I've downloaded the new release, my EA does not work anymore.

I still have to figure out what's going wrong.

Great !

Today new version of MT5 loaded into my computer but nearly 95 percent of my indicators stopped working.

Maybe you just have to re-compile them, have you tried it?

I also have this fault. E.g. the standard RSI indicator does not work anymore. It does not show a graph. And an EA using it can not load RSI indicator (error code 4805). Is it working for someone else?

Now that MQL5 have the matrix library, I recommend that MT5 develop built-in machine learning library to meet the needs of The Times.

With a shared project, we could build it together :DDD

It seems that in portable mode (&Win10) playing sound isn't working correctly.

PlaySound() no longer plays any .wav files

Hi, after switching from Win7 to Win10 or since b.3180 the function PlaySound() no longer plays any .wav files...

Solved - how, I do not know.

After Win-Update and reboot all wav-files were gone, when I copied them back it worked.
