Welcome to the forum!
There has been no end to the "Quick VPN not connecting" threads here on the forum, and there can be a number of factors that will cause QVPN to fail. It has gotten to the point where a fellow engineer has created a thread just for Quick VPN issues to try and keep everything contained in one place. It may be prudent to post your question in his thread that you can find at the link below.
QVPN Thread
However, if you would like to continue the discussion here in your own thread I would suggest the first thing you do is post at what point during the connection process does QVPN fail? For troubleshooting purposes go into the directory that you have QVPN installed which for most people will be Program Files>Cisco Small Business> and go into the Quick VPN Client folder. In this folder you will find a log.txt file. If you can post the output from this file (and please edit out your network information) then we might have a better idea why the connection is failing for you.
