Did you try Internet Explorer or another browser? I can reach the site okay.

No problems here. If you haven't try with a different browser. Or clear your browser's cache and history.

Do as MK says and empty your browser cache. Cookies can expire or corrupt.

Also, if you are trying to access the site via a bookmarked entry use Google to locate the site instead. If successful then delete the prior bookmark and create a new one. Sometimes bookmarks corrupt, expire or are slightly altered by the website..

"browser cache". Not exactly sure that this means. I deleted all history. The link I posted on this forum is from my bookmark results on Firefox, copied and pasted from the toolbar. I tried Internet Explorer and Internet Explorer 64 bit, used Bing for search, same URL resulted and site inaccessible. I have Windows 7, Home Edition.

Reboot router or modem if you use them, If that fails try below too.

@Echo on
pushd\windows\system32\drivers\etc
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
popd
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
del %0

Copy the bold text above and paste it into Notepad. In Notepad click file and:

Save as flush.bat to your desktop. Go to the desktop and Double-click flush.bat file to run it. Your computer will reboot.

Note: For Windows Vista or Windows 7, right-click flush.bat and select "Run as Administrator".

browser cache would mean cookies, temp internet files, history, in IE internet options under tools then delete temp files clear history clear cookies or use a program that will do it for you like ATF
ATF-Cleaner

your link addy works fine for me with firefox in linux.

having another browser on any pc is advisable so that if IE fails and it does you still have a way to access the internet. I use firefox all the time on my computers many great add ons for it.

My modem is DrayTek Vigor 2500. Rebooting the modem is turning it off and then on after a minute or so?
I use Mozilla for my browser 99.9% of the time and Google is the default search. I will try the suggestions as time permits.

That would be correct.

I turned off the modem and did some other things for a half-hour before turning it on again. It now works! I do not understand why the modem was the problem, but unquestionably it was.
My gratitude to all who responded.

anytime you run into problems you are not sure how to fix one of the first things to try other than of course a reboot of the pc is a power down of the modem, router and all things connected. Usually wait about 5 mins or so then the power up sequence should be first the modem let it get fully up, then power up the router let it get fully up, then your computers. That will flush out the info and let it get new info which will often times be the solution.
