DDE MT4 to Amibroker

YES: I have read & re-read the thread commenced by Dan June '17.
I " " " " http://www.amibroker.com/dde.html

I have also deleted, downloaded & reregistered v 5.9 more than ten times on this W10 system.
Even worse, I got it to work earlier this year!

I list the position below & would be most grateful if someone would be kind enough to advise where I am going wrong.

DDE is enabled on MT4 and, I believe, is connecting because the box to the right of the yellow 'wait' headed 'Performance' indicates a varying % for load factor.

Under Symbols/Info Continuous quote - Yes: Use only local data No.

Database Settings:
Database Folder: C:\Program Files\AmiBroker\DDE
Data source: DDE universal plugin
[ DDE plugin listed under C program files AmiBroker Plugin & downloading the plugin again results in the warning only I DDE.dll may be in the folder.]
Local data storage - Enable
No. of bars - 100000
Base time interval - tick

Configure:
DDE server -MT4

No doubt I have missed something obvious, but I should be extremely grateful if someone could offer correction.

Hopeful thanks,
