cannot add web pages!?

Hi all. This may be a really dumb question…but I have a problem: when I am looking at a web page that I want to save to devonthink, on safari, i go into safari’s menu, click services, and find all the devonthink options are greyed out, so I can’t use them. Can anyone tell me what I am doing wrong?
Thanks.

If you have just installed DT on your computer in the Applications folder, it’s necessary to logout/login or restart for its Services to become available. Note: the application must be installed into the Applications folder for services to work.

Also, if you have two versions of DT in your Applications folder – example, you were using DT Personal and have now installed DT Pro – they will “compete” for Services. Only one should be in the Applications folder.
