Once again a ZA update crashed my system, this has happened too many times with too many upgrades over too many years. I've continued to purchase ZA because it is the only program I've found that also controls outgoing communication, I think its time to start looking around again. Logging on today I was prompted that my existing (purchased) version of ZA is no longer supported and the update is required, I followed the prompts, accepted to allow ZA to uninstall/upgrade, then it threw a BSOD which Win8 couldn't recover from or repair. After a series of looped repair attempts I was forced to refresh my installation and get to spend my day reinstalling and configuring. Not amused.
