Managing fixed width/delimited specifications (Access DB)

Hello,

I have a quick question (hopefully)

I am allowing my users to create Access specifications through my software but when I try to use it to load a text document I am getting an error:

"The fixed width specification "File_Fixed_Spec" contains no column widths."

Any idea on what this is? Has anyone used Access specifications to load large text files?

Thanks in advance!

Anyone know how I can manually edit the MsysIESpecs and MSysIEColumns tables manually?
