suddenly not working anymore

This plugin was working great a week ago when we moved our site from wordpress.com to www.ads-software.com (domain: intentionaltravelers.com) and changed the permalink structure. I’m not sure why, but now the redirects aren’t working.
I had request: /%year%/%monthnum%/%day%/%postname%/
Destination: /%postname%

After the problem started, I tried to redirect some pages manually and that does work. (Example: /2014/09/15/travel-hacking-with-the-alaska-airlines-award-program/ to /travel-hacking-with-the-alaska-airlines-award-program/). But I really want to use the tags instead so I don’t have to manually enter over 100 posts.

Any ideas would be very much appreciated. Thanks!
