I am in Maryland

An AFFIDAVIT JUDGMENT was ENTERED on 09/27/2006, For a credit card that I did not pay for. I called them last year and arranged to pay them in monthly payments and I started paying them but I ran into problems and havent been able to since. I received a court letter last June that says the court granted a MOTION TO COMPEL ANSWERS TO INTERROGATORIES, and the the suing credit company (Atlantic Credit and Finance) mailed me questions to answer which I did not answer. Now I find out that there is a Show Cause Hearing scheduled in this case from a Judicary Website and I am wondering what this means. Am I in trouble for not answering these questions, should I show up at this court date? I am currently on probation for a DWI will this affect my probation? The court date is Monday, Thanks for any help.
