How do I get my drivers licence back after 17 years?

Ok in 1996 I was charged with a felony DUI. I was sentenced to 6 mon in jail that I served. When I got out I moved to the state of Nevada with my P.O's consent. I was told I could enroll in an out patient program and to attend AA meetings for one year with monthly reports to my P.O in Ca. and told to report to probation in Nev. I reported to the Nev pro. they took my name and number and I was told they would contact me. Meanwhile I enrolled in the out patient program and attended AA. I graduated the out patient program received a certificate of completion and everything about that time Nev probation contacts me and says California never told them a felon was coming to their state and they are sick of this happening and they won't accept me there so tell my p.o. So I do just that I move back to California I try to get my license and they pull this I have to complete a first offenders DUI program I tried to explain the story but nobody can find any records of my probation or anything but on my dmv record it says i have to do the first offenders program. so I tried to enroll then they told me to get a print out from dmv to enroll so i did. Ilive in sonoma co. now the offense was in placer co the DUI program says i have to contact the co that i got the DUI in to get the probation reports but when i do they have nothing so I'm stuck.I haven't had a drink since the year 2000 13 years now I hate not having a license please help!
