Joined only yesterday, so be gentle! I saw a thread (albeit from 2016) about how to update Wooshbuild; I've pressed green button, clicked on 'WB Importer' and . . . nothing, just nothing happens, goes back to normal tv channel and when I press ANY button on my remote I get that white cross on black background top right of picture - as in no commands accepted. So then I restart Zgemma box and try again, and exactly the same thing happens. My question is: do I really need to update Wooshbuild?
