Can't initialize MT4 bridge with LMAX demo account

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
Z8 .x ..
ZorroMT4.dll => MT4 (demo) plugin mounted
Login MT4 (demo)..
!Can't initialize MT4 bridge!
Check account number 25400000412
Can't connect!

Can someone kindly help me solve the problem?
Thank you

No one who had this problem?

I am having the exact same problem. I still have the problem after trying the below:
Upgraded Zorro to 1.58
Installed latest MT4
Re-applied LMAX account settings
Received new account settings from LMAX and still no joy

I can't spend anymore time on this, would love to know what it is!

I think there are limitations in source code to block the bridge with brokers who are not sponsors

Hi mrticks, I get the same message as you,

!Can't initialize MT4 bridge!
Check account number ...
Can't connect!


but I have the problem that I can only connect to MT4 demo accounts, not real accounts. I use MT4 with FxPro. I have Zorro S 1.58, so this should actually be possible, shouldn't it? What am I missing? Is any additional installation for S with live mt4 accounts necessary? I installed the DLL file that came with S subscription. I know it is working since I am able to open several instances of zorro. Connecting to FxPro MT4 live accounts however seems not possible. Any help on this issue is greatly appreciated!

Hi, please help, anybody?
Thanks!

First check your account number. "25400000412" does not look right, since MT4 accounts have normally 8-digit numbers.

But if the account number is correct, something else possibly went wrong. You got support time with Zorro S, so you can contact Support for help. They also have a service to install the MT4 bridge on your PC by remote access.

I have the same problem with my MT4 broker. My demo account also has 10 digits. Anybody has solved it?

Definitly it happens with some brokers MT accounts with a long numbers (10 digits for MT account id). It must be a bug in the code.
Anybody knows how to report a bug?

Maybe the MT4 bridge expects a 4 byte value which is enough to store 8 digits, whereas for 10 digits you need an 8 byte value.

MT4 account value is 8 bytes (long).

Thus "25400000412" could be a valid account number.

I do not think that it is a valid account number to a demo account. It can be a valid number of a real account. If you do not see "Demo Account" in the title bar, it's a real account for MT4, even when you cannot trade with real money on it.

You can anytime open a true demo account unter the MT4 "File" menu.
