I am new to using Presence, and have tried several times to do the exercises included in the sample files, and keep getting an error message when running the model. I have also used my own data, it appears to work when I use 1 group constant model, however in the custom model (for my own data) it has been giving me the error message and saying to check .pao or .dm files, however when I try to check these files, I cannot open them. I am sure I am doing something wrong, but I cannot figure it out. I have removed the old program and downloaded a new version as well and keep getting the same error message.
Thanks for your time.
