A greeting to the whole forum.

I installed Zorro v. 1.58.0, but when I try to connect it to the MT4 demo account of LMAX I get the following message, despite I having followed all the instructions of the User Guide:

Zorro 1.58.0 Trading Automaton
Made by oP group Germany 2013..2017

ZorroMT4.dll => MT4 (demo) plugin mounted
Login MT4 (demo)..
!Can't initialize MT4 bridge!
Check account number 25400000412

Can someone kindly help me solve the problem?
Thank you
