I have got Avetix finally working. Avetix were fairly quick in replying to my inital support email. I had missed the reply amongs the big amount of emails I receive. They told me to redownload Avetix as a new version had been released which fixed the update issues. This did not help, initally. But after reinstalling Avetix just now, the initial update completed without issue, and Avetix is running as it should. Avetix support offered to diagnoise my problems remotely via TeamViewer. I've been busy the last few days and was not able to schedule a time. Of course now, there is no need for that, but they definitely deserve credit for trying to help fix the update problem.
