|Have you looked in your hosts file to see if it is blocked there?|
Click on Start > Run and copy / paste the bolded text into the run box and hit enter (if C drive is where the operating system resides):
When the window opens double click the file named HOSTS, use notepad to open the file.
There will be alot of entries here that Spybot Search and Destroy has added, so it will be easiest to use the search function to see if a somethingawful entry exists.
Click on Edit > Find at the top of the window and type in somethingawful then hit enter.
If there is a match highlight the entire line starting from 127.0.0.1 and delete it.
This should give you access to the webpage.
There will be a reason why Spybot edited this into the hosts file, so you need to be certain you are safe visiting.
If you have no luck with the above steps try flushing the DNS resolver cache.
Click Start > Run and copy the bolded text below into the Run box and hit enter:
cmd /c ipconfig /flushdns > "%userprofile%\desktop\flushdns.txt
A window will pop-up then close, but a text file named flushdns will appear on the desktop, you can have a look to see if your DNS cache was successfully flushed.
Try again to see if you can get access to the web page.
