What happens if I was given the wrong information about the length of my stay?

My husband and I were married 10 months ago, in may 31 he got visa U.S. on J-1 Internship Program, for 12 months, Making documents for me, J-2 visa.The question arises as to affect the decision for my visa j2 after what I had in 2007 overstayed Work &Travel; stay for a month. I was explained that I can stay in USA 5 months (4 working +1 travel ) But I didnt know that correct is 4 months, the company did big mistake a lot of students were misinformation, resulting in the following year 2B refuse at the embassy.(visit my friends.) Then found out that I was not alone who had received false information and came to try second time, I was a failure and in the second time in the same year. Already in 2011 I married, I work. Probability of failure?
