It is a problem with the pz2 file, but easy to fix. :)

Open the file in a text editor, and at the top you'll see this section at the very top:

{

version
 {
 number 7.2
 }figure
 {

---

Here is what it should look like:

{

version
 {
 number 6
 }
figure
 {

---

Simply place the cursor between the word figure and the bracket and press ENTER, save the file and it should now work. :)
