dv 2010 winner with legal issue.... help

[flexjames]

My spouse has been selected for the DV 2010 green card lottery. Her
interview is due in the month of July. All our paper work is in
perfect order. unfortunately i have a brief issue in my past. I
visited the US in march of 2000 on a B1 visa then changed it to a F1
visa. The F1 visa (from August 2000) was for 6 years but i did not
enroll in school. I there after departed from the US on my own accord
in October 2001 to join a local university in my country which i
progressed to complete. Its been been 9 years since then. I was never
in an any trouble while in the US neither was i deported or arrested.
SEVIS was not active at the time. I left willingly. The only way the
ins would know i was illegal is if they call the school to check on my
attendance.
Do they call?

Does this mean i as a dependent/ spouse of the principal applicant
don't qualify? Do i also put my spouse chances of getting the green
card in jeopady as she has a perfect record. She is a graduate with a
good job and has never been to the US or even the US embassy to apply
for a visa.

Please advice
