No problem with running simulations: they work OK for me at the moment.

@andyfierman it looks like if my account is considered a bot, I'm thinking of a DDos attack protection or something, I'm in mexico, and this happen even if a change computers, it happen in my home and in the office. I can get only a couple of simulations in the day.  

@otakorp, Your project is private so only you can see it. If you can make the simulation public and share it or add me to your project so I can run it privately then I could see if it runs for me.
