Spyware Blaster not playing well with Panda AV/Firewall

Hi,
I recently started using my Panda Antivirus Platinum Firewall and I've found that if Spywareblaster is activated and protecting my system along with the firewall then my internet connection stops working. If I disable spywareblasters protective features with the firewall still engaged I get my connection back. Does anyone know of a workaround for this or why it happens? This also happens sometimes when I activate the SpyBot S&D resident. Sometimes it works fine with the SpyBot S&D resident engaged.
