Quicken Essentials can't import OFX file

Issue summary: 
I converted a csv to ofx, but when trying to import into Quicken Essentials I receveived an error notice "Unable to read the selected Web Connect file. Please contact your financial institution."  Previously I used your converter at http://csvconverter.gginternational.net with no problems, but that converter doesn't convert "Category" to OFX (this is essential for me, and why I was trying the .biz site to see if it works).

Quicken reads QFX (QUEBEC foxtrot X-ray) but not OFX (OSCAR foxtrot X-ray).  Suggest use of QIF file type.
I see more people reporting problems importing into Quicken, the problem is I don't have a copy of Quicken to test it, have you got a copy that I can use to reproduce the problem?
