I'm not even clear on what you're trying to do. I assume your problem is that Jet/ACE can't handle a UNION with that many SELECT statements.

If you have 64 identically-structured tables and you want them in a single CSV, I'd create a temp table in Access, append each table in turn, then export from the temp table to CSV. This is a simple solution and shouldn't be slow, either. The only possible issue might be if there are dupes, but if there are, you can export from a SELECT DISTINCT saved QueryDef.

Tangentially, I'm surprised Maximizer still exists. I had a client who used to use it, and the db structure was terribly unnormalized, just like all the other sales software like ACT.
