Selenium Driver for FireFox: failed to start up socket problem

On C# i've got a code which using Selenium WebDriver and Firefox to do Browser Automated testing. The program work well on various Windows. But on one Windows 2008 Server it doesn't work. This is the example of code when I've got an exception error: using [login to view URL]; using [login to view URL]; .... IWebDriver driver = new FirefoxDriver(profile); <- at this line I've got Exception. Failed to start up socket within 45000 ms Maybe the problem is in firewall settings, cause something blocks connection between selenium and firefox browser. We will work in that way: You send your test files, i run them on destination machine and send you back your logs. You analize logs, patch code and send new version. When your code works fine, i award project to you and pay. Maybe you can advise what to change on that machine and if it works i award projects. If you help me to solve this problem I'll pay you 30$.
