I haven't contacted BT but I spent most of the afternoon trying to sort the problem out. I have partially sorted but I'm not really sure how as I tried so many things.
What I did find was that by using chrome rather than Safari I could get into my Cloud account via MyBT and I made some changes like stopping automatic log in. Fortunately I also had the old version of Cloud backed up which I downloaded but as stated before wouldn't work because of the new version being installed. Eventually after something I did in my account must have worked and stopped the new version running because I was able to log into the old version, although I did keep getting the new version log in window pop up and there was no way of closing it (the red cross wouldn't work). This meant I had to make it as small as possible and drag it out to the side which was annoying.
Anyway at this point I noticed that in the top right corner near date time etc where there are a few small icons there seemed to be a larger gap between two of the icons, I clicked on the gap and there was the BT Cloud icon! Now by this point I wasn't bothered whether I never saw BT cloud again and I have photos backed up elsewhere so when the icon gave me several options including uninstall I did and the new version was gone including the irritating log in box...
I still have the old BT cloud but I have switched off automatic sync because for the last week it has saved rubbish, like individual logos off letterheads as photos. I am leaving at the moment but might get rid of it all together, especially as each time I log in it keeps trying to get me to update to the latest version.
