Seems to still be working for me. I've had that happen a lot with other workflows, though.
Eventually I learned to open the Workflows preferences, select the workflow in question, and click the spider icon on the top right to enable debug output (and changing the dropdown in the console to "All Information"). Then I trigger alfred, type the workflow keyword, and see what information it outputs in that console area. Helps me see if the workflow is bugging or even being triggered at all.
