Closed Unassigned: "Value cannot be null. Parameter name: path" exception [2079]

When streaming for more than one word at a time, a TweetinviException returns that says "Value cannot be null. Parameter name: path". I looked for the error from the "Watch" in visual studio Debug Mode and found that the error's source is "mscorlib". I always get this error at first stream request. After i get this error and re request stream, error does not happen again. How can i solve this problem?

My Target Framework is 4.5 and building in visual studio c#. Also my tweetinvi version is 0.8.3.1

Also my StackTrace is like below:
