I got popped in a nearly identical way about 12 years ago. Had a fine I paid late, didn't read the fine print on the notice the DOT sent me, four months later I get pulled over and the cop informs me of my suspension. Unfortunately, you not only had to pay the fine, but you had to get a document from the courthouse and take it to the DOT headquarters in Des Moines, or else you'd lose your liscence anyway (for some reason it take 8 or 9 months for the DOT to find out you've paid a fine!). Nevermind that the DOT never informed my that my lisence was indeed suspended. The cop was cool though, he wrote me out my ticket, and said "Now I can't let you ride this thing home, but I'm going this way and I won't be back for a little while, so you can walk home or whatever..." The judge wasn't so cool. My lisence was suspended and I was driving, case closed. Didn't really cost that much, but don't expect your insurance company to be impressed... :fact
