how come google chrome isnt working?

[613]

when i went on google chrome it said Unable to access the network
Google Chrome is having trouble accessing the network but the internet is working fine how do i get it to work again?
it also said:
This may be because your firewall or anti-virus software wrongly thinks Google Chrome is an intruder on your computer and is blocking it from connecting to the Internet.
Here are some suggestions:
Add Google Chrome as a permitted program in your fire-wall's or anti-virus software's settings. If it is already a permitted program, try deleting it from the list of permitted programs and adding it again.
Error 138 (net::ERR_NETWORK_ACCESS_DENIED): Unable to access the network.
