Visual studio 2015 update 2. Team Explorer not working
<p>I updated VS2015 to update 2. </p>

<p>Upgrade process finished fine, but after launch a lost access to Team explorer.</p>

<p>There is a bug with the following callstack instead.</p>

<pre><code>    An exception was encountered while constructing the content of this frame.  This information is also logged in "C:\Users\volkov.a\AppData\Roaming\Microsoft\VisualStudio\14.0\ActivityLog.xml".

</code></pre>

<p>I tried repair and reinstall. No result.</p>

<p>Also I'm getting exception on launch:</p>

<pre><code>---------------------------
Microsoft Visual Studio
---------------------------
Error HRESULT E_FAIL has been returned from a call to a COM component.
---------------------------
OK   
---------------------------
</code></pre>

<p>What else could I check?</p>
