what I'm I facing in case of driving with revoked licence in kansas and illinois?(licence IL, stopped in KS)

I had DUI in NJ over a year ago (licensed in IL). Completed all the NJ court orders, paid fines, completed IDP program and finally received the letter of restoration of my driving privileges effective june 1st, 2009. I was sure everything was fine. Then few days ago I've got pulled over in Kansas for speeding, and arrested for driving with revoked licence. Now I don't know what I'm facing and where. I wouldn't drive if I knew licence was revoked in Illinois. I have a letter of restoration, proof of completing IDP course. Will it help in the court in Kansas? If I hire an attorney do I still need to go to court? I'm in Key West now.
