Thank you for the feedback. My team is trying to reproduce the problem in order to help you with the issue. We tested the extension in Visual Studio 2010 Pro SP1 EN, and a localized version of VS2010 Pro. It works well in our test environment. Would you mind sharing some infomation about your running environment? Did you install the latest VS2010 Service Pack? What's the language of your VS 2010 Pro? When does VS crash? A screenshot will be very helpful. You can email us at email@example.com. My team will have the highest priority to handle this issue as soon as we receive the information.
