I have version 18 build 373 and opened it last night to start a project. I got a message saying a major update was available so I clicked to download. Took a really long time to get around 50% and then the status window of the updater disappeared. I closed the program and reopened and again got the update prompt. I clicked to download but again same thing happens. Have done this 5 times and wasted hours trying. What is wrong with the updater?
