Unfortunately, you do not appear to be eligible to recapture the old priority date, because you fall into a different preference category. Had you not been married at the time your mother filed the second Form I-130, you would likely be able to recapture the priority date. Were you married at the time the visa became available? Did you notify USCIS or the NVC? If so, you could possibly argue you were in the same preference category.
