Trying to import accounts in to V3
I tried about 20 sample records and it worked fine.
I then added categories and industry to the main CRM app to include all the
items in my data.

I ran the import, it goes to where I match up the items, then as soon as I
click import I get "Invalid Argument" dialog box. Nothing else happens and
that's it?

Anyone have an idea whats going on?
