Access vs. Filemaker Pro vs. SQL Server

The only DB experience I have is (unfortunately) with MS Access.  I'm now creating a software application that interfaces with a DB, so I just went with what I know (Access).  But, I don't really like the user interface, especially for dealing with relations.  Also, it has a very limited range of data types (no real numbers, Booleans use a strange convention for storage, etc.).  And most recently, I've run into an intractable problem whereby I cannot programmatically add or update records (covered in a separate post).  So, now I'm seriously considering moving to another platform.  The two I'm considering are Filemaker Pro (Is that different from Filemaker?), and MS SQL Server.  But, I know essentially nothing about either.  So, I'm looking for some advice on the trade-offs / suggestions for which way to go.  Also, of course I'm wondering what is involved with importing / translating my existing DB to one of the other tools.  (If it matters, the DB has 38 tables, and about 200 fields, but very little data so far.)
