Check your IE:Tools:Internet Options:Security tab.
Select the trusted sites icon and check the security level. If you're set high, try to bring it back to medium, or go into custom and tweak it from there.
Or
Copy your link (
http:www.ebay.com) into the buffer.
Go to "Start > Settings > Control Panel > Internet Options > Security > Trusted Sites > Sites". Paste your link in the upper window and click "add".
It may "choke" on your link because it wants a secure connection. Add an "s" to the "http
s:...". Maybe that will work. Maybe that is why it hasn't been working in the past.
If there is already a similar link in there, delete it.
See if that helps.
