Has anyone else experienced problems loading up test sets with the new TestRunner?

Has anyone else experienced a problem running a test set since the update? 

I am using a SAAS version of QAcomplete and since the update I am now unable to run one of my test sets. The set consists of 79 tests. I have tried to continue a paused run of this set as well as a new instance of the test set, both will open the new runner however nothing appears except the timer. After a couple of minutes I receive an Ajax error (see screenshot).

I have tried this in both Chrome and Firefox but neither seem to work.

If anyone has any solutions on how this can be resolved it will be greatly appreciated as I am 95% through regression testing.
