since the site is working ... you probably just need to clear your cache and retry ...
go to CCleaner.com ... and download CCleaner ... very useful ... install it ... and then run it ... then go to domaintools and try again ...
if problem persists ... restart your computer ...
if problem still persists ... throw your PC out of the window ... and quickly run downstairs and try to catch it ... IF you fail .......... buy yourself a new computer :lol:
EDITED TO ADD :lol: : I just went to the site and the site works but the login doesn't work ... so it is just something temporary ... I hope you can read this :p
