Answer

Unfortunately, under the law, if you take a "significant step" toward committing a crime, you are guilty of attempt, which is punishable as if you had completed the crime. The fact that you made arrangements and drove to the location are significant steps, so there's not a lot you can do.

There are a couple of post-conviction remedies you could try if your conviction was defective for some violation of your constituitonal rights (ineffective assistance of counsel, for one). If you are still on probation, you can file a post conviction petition. You might also be able to file for a writ of error coram nobis, which asserts that your conviction is fundamentally against justice. I don't know what went on with your case so I don't know if you actually have those grounds, but you might want to consult a criminal attorney who is experienced in post conviction filings to review the records and see if you have a basis. Otherwise, at this juncture, there is not much else you can do about your conviction.
