cannot access website

At home I work on a Mac - http://audacityteam.org/ website will not load. I tried it with Safari and Mozilla - I tried it on my desk top and lap top. I tried clearing history, cookies etc…nothing! I get an error message whenever I try and access the site

At my job I work on a Dell using Explorer and the site loads in just fine (I am on that system now which is how I am able to access this forum)

I need to be able to access the site from my Mac - does any one have any idea what could be going on? Should I try installing Explorer on my Mac?
Thanks

No. You should tell us what the error message was.

Also, how are you connecting? I have 786/3000 DSL Extreme at home and a minimal firewall.
Are you using a virus software?

I’ve just checked and http://audacityteam.org/ is loading fine here. Perhaps there was a network problem when you tried.
If the problem persists, please tell us precisely what the error message is.

It was security issue on my end - all is fine, now. THANK YOU for the replies.
