Running Simulation Error in Client - WONT WORK!

Running simulation 599733d97ba94beca60508691d40978b, chunk 14860

599733d97ba94beca60508691d40978b Error

I keep cancelling - and have uninstalled and reinstalled - but still get this error as soon as the client initializes.

What do I do???

Go to Not Available and follow the instructions for clearing your queue in the lower-right. That should resolve any issues like this.
