Yes - When I do, I get a message that "TV Guide is currently not used by any channel, so no update was necessary. You can assign an EPG provider by clicking into the EPG column in the Channels view." What was unclear was that in the Channels view I needed to click into the column for a specific channel, not the column header. When I did that, It allowed me to download the lineup for all the channels and all looks normal now.
The TV Guide information used to be pretty detailed - specific information on each episode of many shows, color coding to distinguish between channels and shows. Now I have trouble with sporadic updates, no color coding, and very little or no episode detail. Did TV Guide downgrade the product that we get via licensing in EyeTV 3?
