Grey Lines covering my document

[DESTIN KOELSCH 0]

I am trying to edit a document in Nitro 13, but when I open a specific document, there are grey boxes that I can't edit or move covering parts of the doc. I opened the same document in Nitro 10 on a different computer and did not have the same issues. I've already tried settings, preferences, etc. Very unhappy with the support I've gotten for this and no, I do not want to buy VIP. I just want you to fix what I've already bought, or allow me to download a previous Nitro version.
