Problems with Ninja Trader 7 after Windows 7 Update

[jgomez6K]

Hello, I am having troubles with the data feed connection.

Ninja Trader tells me that Login failed and that I should check the account parameters.

All this happened after having a problem first with Ninja Trader itself. Windows made an automatic update for my Windows 7 operating system, after that update I tried to launch Ninja Trader, but an error appeared telling me that Ninja Trader stopped working. I restart the computer several times and the same message kept appearing.

So, I had to remove Ninja Trader and download it and reinstall it again. I think I installed a newer version than the one I had. The version I installed it is 7.0.1000.6. After installing it the new version and openning the platform then finally it launched. However, when I tried to connect to the zen-fire service to obtain the real-time data, the message that I mentioned before appeared.

I do not know if this is becuase I might have installed a different version for Ninja Trader.I deleted the Zen-fire account and created it back again. I even already got online support with Mirus, the data feed provider, but after doing some testings, they told me that the info of the demo account they gave is correct and the problem might be with relation the Windows update and Ninja Trader. One of the updates Windows did was the Service Pack 1 for Windows 7 and other securities updates. It also updated the security for Microsoft .NET framework 4 Client Profile.

As I said I can now open Ninja Trader, but I cannot connect with the Zen-Fire data feed and I already tried with two different accounts. What should I do?

Thanks in advance
