When I import to Corel it tells me the file is corrupted.
I opened it in Drop Box. I then went to print and used the option to save it as a pdf.
Huge file apparently that made my CorelDRAW hiccup and gasp for air a bit, but it did open, however, like I said, it was missing the box at the bottom with a reversed-out "Celebrate"
Here's a screen shot of the whole thing to tease you.
Then, there's a detail shot which shows why this is so crazy. (and that's not the only overly complicated logo)
