Looking for earlier versions download

Hi, we are currently using v8.0.6 and occasionally experience a crash of monitoring_thread2.exe. Tried several things including fresh install but no luck. Bummer is that it works for days, even months and then suddenly pop-it-goes. Looking through release notes I've found Release 8.0.9 supposedly fix "Windows Sleep function that could cause random failure of monitoring_thread2.exe". Although I am sure PC is not going to sleep I am having high hopes but it seems that older releases are not provided on the site. Does anyone know where to download or perhaps do you have a copy of Release 8.0.9 or 8.0.10 please? Our licence goes only up to 8.0.10 and upgrading it is unlikely.
