Still getting a blank screen for this link too (the filter they have here at work can be funny sometimes), so I took the first part of the URL you included (
http://lmi.ides.state.il.us), cut/pasted it into my browser, got the starting screen for the Illinois Department of Employment Security (IDES), and then tried to click my way through the various trees to try to find the data you probably meant.
Found a PDF called LAUS_YTD_STATE[1].pdf . It contains the data:
2011 YEAR TO DATE ESTIMATES FOR THE STATE, METROPOLITAN AREAS, MICROPOLITAN AREAS, COMBINED STATISTICAL AREAS
COUNTIES, CITIES, LOCAL WORKFORCE AREAS AND ECONOMIC DEVELOPMENT REGIONS - NOT SEASONALLY ADJUSTED

Is this the one?
I haven't a clue why this PDF says different things from the U.S. Dept. of Labor PDF. The numbers are in exactly the same ballpark, from 5.9 million to 6.05 million persons employed in various months, but why the figures for each months don't match, I don't know.
This newer PDF I found in the IDES site (Is it the one you were trying to point out?), contains the word "ESTIMATES", which the Federal one doesn't. But that's pretty thin. The Feds have been known to use estimates too, though they usually say so when they do it.
We may have to wait for ProudLefty's report on what the U.S. Department of Labor tells him after he reports to them that their numbers are wrong.
