I would call an attorney in the city where the court is in Colorado and ask him or her. The consultation should be free. I do not know how Colorado treats misdemeanor bench warrants, but in California, an attorney can appear for you (you do not need to go to court) to have the warrant recalled. The attorney in Colorado ought to find out just what is the nature of the clerical error first, because if it is that the court there needs proof, for example, that you paid a fee, then you may be able to fax or e-mail him or her the receipt showing payment of the fee. Then when he or she appears to have the warrant recalled, the receipt can also be presented to the court to resolve the clerical error. If the clerical error is something else, at least he can tell the court what you know about the issue and that you are looking into it, if you are necessary to resolve the issue.
You should be discussing this with a local Colorado attorney who is more well versed in this area than any California attorney. As stated above, in California one doesn't need to appear to have a warrant recalled on misdemeanor charges. Good luck.

The response above is not intended as legal advice since it’s impracticable to provide thorough, accurate advice based upon the query without additional details. It is highly recommended that one should seek advice from a criminal defense attorney licensed in your jurisdiction by setting up a confidential meeting. Moreover, this response does not constitute the creation of an attorney-client relationship since this message is not a confidential communication because it was posted on a public website, thereby publicly disclosing the information, which is another reason to setup a confidential meeting with an attorney.
