I did a search and found a couple threads that seemed to have the same problem, but I didn't see a solution posted.
I have an MS Access database. It's super simple... a single small table. When I try to use llblgen, everything seems fine, except that llblgen doesn't seem to see that table.
I added a second dummy table as a test and it didn't show up either.
Interesting... as I was typing this note I wanted to make sure I included all the info I could. I was about to type "The only other difference from THIS project and other projects I've done with llblgen is that I unchecked the "Views" and "Stored Procedures" checkboxes under "Elements to read from the database schemas" while creating the project.
I just went back and tried to create the project again and I left Views and Stored Procedures checked (in addition to the "Tables" option which had previously been the only option I chose).
...and now it sees my tables!
