Issues with TestStudio 2014.1.410

Hi,

We are trying to upgrade from TestStudio 2012.2.1420 to 2014.1.410. We also upgraded to Visual Studio 2012 Ultimate. We are running our tests on a remote server from Test Manager. I also installed Visual Studio 2011 Ultimate as it was complaining on missing dll as shown below.

After i installed Visual Studio 2010 Ultimate the above exception was not longer thrown. No sure why we need Visual studio 2010.
 
The main issue is when we run a single test, the test starts executing immediately but once we add about 50 tests to the suite the tests wait in the queue for nearly 4 hrs before it actually starts executing the tests. We are not sure how to debug this issue. I am attaching the log from Telerik and also a screen shot from Test Manager when it is waiting in queue for 4 hrs. Please let us know if there is anything we should be looking at.

Thanks
