CDR files to PDF in large quantity

We have close to 11k of CDR files that we need to convert into PDF files because a great number of these CDR files have multiple pages in them. I'd like to be able to do this as a batch process.

I've tried this product called FoxPDF CDR to PDF converter, but it doesn't work. All it does is convert it to a PDF file, but inside the file there is  nothing but a very large red pixelated shape in every single PDF file it creates. I've tried it on about 20 CDR files.

I couldn't seem to find a macro that can batch convert CDR to PDF on

Does anyone know of a great way to do this on a large number of files?
