Antispam 2.1 Download stuck

Thank you for the new AntiSpam v 2.1 program

I was looking forward to having it working but the initial download of emails is stuck at “receiving message 203 out of 213” according to the icon message on the tray bottom right hand corner and no more emails will come in whilst this stalled process remains stalled

Anyone have any suggestions how to clear the blockage

I had to remove the antispam firewall setting completely otherwise the program was just like the previous version installed but inoperative
