Web Design and Graphics Room. Thread, Sierra Web Artist

Hello
For the past 5 years I have been using Sierra Web Artist to publist my web site. It has always worked withot fault. I know its an old program but does exactly what I want.
Since changing my Fire wall From Zone Alarm to Comodo I cannnot upload it.
To do so I have to turn off my Comodo fire wall, upload and the turn it on again. I get no error message from Comodo, Web astist just stops working
Anybody got any idears?
Grumps
