My comobo not updating

Not sure where i have to post this so I pick this page to do so. I have Comobo Internet security Premium and I been trying to get it to update but every time I try to I keep getting
Status: A connection with the server could not be established
I have this on my laptop window 8.1
I don’t know what this means what so ever 6 months ago it was working fin.
On my desktop it updates but don’t really update at all. It lags on 90% and stays there I let it run for hours and it still did not update. My desktop is the same has my laptop 8.1
I tried re-down loading it and re-stalling it on my pc up it keep crashing my pc I had one hell of a time
getting it to start after doing that I rolled my pc back. So if you can help me with this or tell me what to do to fix this I would really like it.

Mine wont update either and re-installing did not work.

Please try reinstalling CIS following Most Effective Way to Reinstall CIS to Avoid/Fix Problems by my colleague Chiron. It will provide a reliable clean starting point.
