Data Merge rejecting all source files
I have used Data Merge in the past, but not for a while. I am trying to do a simple merge project, and could not get Merge to accept my data file. So I have worked backwards, with simpler and simpler files hand-edited in Notepad++, verifying that they only contain data, commas or tabs, and paragraph returns around one-word data... and ID is consistently telling me "this file has no records or is not a compatible type."
I've tried direct CSV and TXT exports from Excel, and hand-edited versions of both. I even found a file from a prior project a few years ago. Can't even get ID to open the Import Options menu on any of them.
Is 17.3/Win broken on merges? Could someone upload a simple test file they've validated?
