You are too kind, I hardly did anything.

The MT4 connection is fundamentally odd because it involves inter-process communications, using a "backdoor" in MT4.

Lots of things need to be verified:

* Did you run the EA on your MT4?
* Is there a smiley face on your MT4 chart? Does it say that Zorro is connected?
* Did you close the chart with the EA and start over?
* Do your account numbers and passwords match?
* Do you have the correct version of the EA installed? Are you **absolutely** sure you have the correct version? I mean you must delete your EA and copy it over from your **current** Zorro installation to your MT4 installation.

If you cannot figure out what's wrong after reading and re-reading and re-re-reading the documentations, perhaps you should evaluate whether paid services are worth the cost.
