Corel spells words backwards when it opens a PDF

Has anyone else run into this? I tried to open a couple PDF's in Corel Draw X3. They opened beautifully, all the graphics were in place & the spacing and typestyles were all correct. But every word was SPELLED BACKWARDS. It's not that it was a mirror image; each character was perfectly formed but, for example, "Word" was spelled "droW". I cannot figure out any way to correct it.

Does anyone have a solution?

PS - The original was produced in CorelDraw X3, and published to PDF. In case you're wondering, the original *.cdr was damaged, but we have the PDF and I thought it would be a simple matter to bring it back into CoreDraw for editing.
