Same here, it wanted to do an update so I let it, downloaded ran it then gives error update failed, I have left it alone every since, guess I will not be updating it, I use different computers depending what type of show I do, this update was on my laptop computer, it is Sony Vaio 64 bit everything is kept updated. Have had no issues either. I also you a desk top computer 32 bit hand build xp for live shows also, when I loaded the procaster it did not say there was an update. But at any rate I will update the procaster until we get an answer, I do not want to start a live show and then it crashes, that is no fun!
Looking forward to an answer to this error problem
Have a blessed day
