avast internet security

i just purchased avast internet security 5.0
firewall will not start.
i am running xpx64 is there something i need to do to enable avast firewall?

Do you try pc reboot?

yes. it is also a clean install

OK I can’t tell, it starts and stops and restarts normally here on Win7/64…I’m definitely looking for people here to discuss this firewall behavior (so, when started, might start a thread about it…)
