What would cause a Program with two Landing Pages and one form to continuously fail during import from one instance to another?

The first form I used, even after creating the identical fields in the new instance, would not import. I ended up recreating it on my new instance. Next import attempt failed again. This time I took the form out and it imported. However, that caused another issue as when I went to edit to add the new form, suddenly nothing was editable nor could I add a new form. Last attempt I used a very basic generic form I had on both instances. Another fail. Any idea??
