Unreliable Corel Draw import cost me big money again

Yet again Corel Draw let me down in a painful way. Recently the errors and problems with importing PDFs are even more cruel as the program seems to importing fine without notifying with any error but for some reason it turns out after print that there is one small letter missing somewhere within one word. Not even space left, no strange postscript errors or change of font that could indicate an error. I had two cases like this in my company within 3 days. Both are expensive large acrylic perspex panels.
For example when I import the below PDF  in Corel  Draw X6 as curves there is a little letter ‘t’ missing from the word ‘Development’ in bottom right corner.
IS Corel doing anything with this matter?
Support as far as I know is only available for 30days after purchase and they still have not replied to the other issues.
