title: Cannot check-in recent code changes to Visual Studio Online
body: <p>For some reason I cannot check in my code to our Visual Studio Online account. Other developers can, but not me. This is the error I am getting:</p>
  
  <p>"Could not find dataspace with category VersionControl and identifier <em>[some guid]</em>"</p>
  
  <p>Searching for any help on the above error is not returning anything meaningful. </p>
  
  <p>This started to happen after I installed Visual Studio 2015 Enterprise. I launched it for the first time after creating a new web application with Visual Studio 2013. I then opened that new solution in 2015 and all was fine. Things began to go awry once I tried to put it in our Visual Studio Online account. When I went to Team Explorer in VS 2015 I selected "Projects and My Teams / New Team Project". This then bounced me over to our Visual Studio Online account in the browser for me to fill out that simple form to create a new team project. I filled the form out and submitted. I then got an error that the project was <strong>not</strong> successfully created. Unfortunately Visual Studio still thinks it was created and it shows up in the list of projects ONLY WITHIN Visual Studio -- it does not show up online. Eventually I just became frustrated and deleted everything related to all that I just tried but then learned that I cannot check anything in now on my old projects! I had other developers test and they still can so the problem evidently is on my machine. I then uninstalled VS 2013 and VS 2015 then reinstalled VS 2013 and am still having the problem.</p>
  
  <p>I am hoping someone can point me to some cached junk that needs to be cleared on my system. :-)</p>
