Hi to you.
Same happened here.
My Internet Security is AVG. Too stringent for its own good!
(Resolved):
This is just a silly step-by-step thing which I did.
If AVG (that's all I have), open Internet Security (square colored icon), thene menu (top right), then Settings (left of pop-up screen), Exceptions (halfway down page),
open 'Browse' (quite hard to see. Grey shaded on mine),
and add any place where Aivlasoft is installed (C:\Program Files\AivlaSoft\* (and) C:\Users\Shane\Documents\AivlaSoft\* (if default install).
After this, press ok and exit.
We're not done yet!
Back into AVG, and Menu (as before) and click on 'components' (top left).
End of the page is 'Enhanced Firewall'.
Open blue 'Customize' text.
On this new page, to to the very end and click 'Packet Rules'.
At the bottom of THIS page (sigh !), click on 'Add', and type under 'name' column.. TCP (13), then 'Allow' (Action column); 'All' (Protocol column); 'Out' (Direction column).
Press OK.
Make sure Enhanced Firewall's button is on (green) on previous page.
Fingers crossed.
PS. Restart PC. (Maybe even un-protect AVG from tray until you get this gorgeous program working!
Good luck.
Going to get some headache pills and go away now.
