I have a problem with Selenium running with Chrome

Question

Good afternoon. I have a web application made in C # vs2010. I need to do an integration via Selenium with another site and I am having the following problems:

When instantiating the webdriver to error chrome, it opens the browser but does not follow in the code to open the page. (No firefox works). It seems that it has some relation in abrir 2 instances of chrome.

Thank you
