I'm having a problem with the Assistant Software v3.8 (and 3.6) crashing on my Mac running OSX V10.10. I've purchased a used Vision+ and while the Assistant opens and connects properly, shortly after it opens another window opens and says it's upgrading the firmware from 3.04 to 3.08. Just as the progress bar indicating a download gets to the end, the software crashes. I've tried reinstalling, restarting and trying to cancel the download without success. Can someone give me a hand? It would be ok with me to not upgrade the firmware but every time I click the cancel button the window reopens and tries again. Thanks.
