It says too many fields defined...I was trying to shrink my field size on an already saved db and it came up with the same problem.  I am using access 2013 and have 100 fields.  I am having this problem with all of the forms, queries, and tables I am making...Am I suppose to save them in a different format or something?

Reply from Alex Hedley:

That seems like a lot of Fields for 1 Table, it might need normalising.

One option would be to backup the database and then run a compact and repair.
If that doesn't work try importing the table into another blank database and trying again.
If that doesn't work you might need to split the table.
