Error 113- Can't update/Internet connection lost

I keep getting an Error 113 whenever I receive notice of an update.
I am running Comodo Firewall free, version 3.12.111745.560 with Panda Antivirus on Win 7 32bit.

You are running quite old version of Comodo firewall. You should uninstall it with Revo Uninstaller in Advanced Mode and after that install v5.

You cannot update from v3.x to v5 using the program upater. You will have to start clean. You cannot copy your v3 configuration to the v5.
