In my install of MTM i can't view plan results for any test plan. Any time I try to view results from testing center Plan->Results I get an error "Application detected an unexpected fault. The given key was not present in the dictionary"
I'm also unable to view graphs of test results from a test run (the pie charts showing pass/fail results).
A coworkers MTM install was able to see these areas just fine.
Now I did recently install Update 2 CTP, and after i was unable to run codedUI tests I uninstalled the update. Ever since then i've been experiencing this behavior. I've also completely uninstalled/reinstalled visual studio 2012 and update 1 and am still seeing the same behavior
