Thanks for all your answers, whilst it may be a server issue, the fact that it is a known issue and they have done nothing to fix it, doesn't instill confidence in the company. Whilst you can still use the product as it was when it was last updated, it no longer updates, which renders it as outdated... Sad really as before this, I had no issues and would have happily renewed, now I'm not so sure...
I have a CCleaner my origional email states that I am subscribed to a multiple payment product the next payment of £19.95 is due on 30/05/2020 but I am now being notified by my CCleaner that my licence is now invalid? I feel gutted that my licence is invalid. what is going on? I have only ever installed it on my own laptop, nothing else, so how can this be?
