@Jhaberman I understand you do not have Lacerte. I understand you use ProConnect Tax. I understand you have received less than adequate support from those that you worked with. I understand that your folder can be different. I would think you could see the files in the folder you do have. Do they match what is in the description I gave you. My suggestion is that a Lacerte support person might be able to convert what you have to what you need to do the conversion to ProSeries. 

You are speaking to other users here that are attempting to help you to get an answer. Maybe @IntuitBettyJo or @IntuitGabi can get you some help.
