Premier 19.5 app has been blocked for your protection

I still have one client on this and am trying to do their accounts. I went to open a support request and it won't open one - tells me to come here. So does anyone know why I need protection (I have a copy of the client's file here so I can investigate issues - the live file is with them in another town)?

So frustrating at year-end to have these issues. I'll call tomorrow when they're back on deck - but just hoped I might avoid what is sure to be a long wait - which doesn't suit my stroke-damaged brain at all. Listening to muzak is detrimental - I usually hang up with other places.

Thanks - and sorry for letting off steam.
