Hi, friends. I'm having some problems here.
It's been a week I get this error, when I try to get to the site with my house internet.
I registered here about a week ago, and this happend right after the hours later! Crazy!
All I did was registering (and I swear that I've never made a registration in the site),
applying for giveaways,
and sending a PM with proofs for the giver which he asked applicants to.
It's really frustrating me when I don't know the reason at all.
I'm not sure that it's right to ask questions like this in here,
but please someone help me!

Sounds like it may be your home connection. The site has been fine for me. You get any problems reaching other sites?

Yes! Problem solved!
It was my wireless router problem.
Searched in the internet and finally solved it.
Gee, was I silly!
Thanks for the reply!
