Conversion Failure - .jpeg to .pdf

I scanned several documents into my computer and they saved as .jpeg files.  I want to convert them to .pdf files so I can email them.  So I went online and subscribed to the Abode PDF Pack for $69.99 a year, which clearly said I could convert .jpeg files to .pdf files.  After subscribing, I then tried to convert my .jpeg files to .pdf files, but EVERY file said Conversion Failure.  I tried doing it several more times, but Conversion Failures EVERY TIME.  Why is this?????  This either needs to be fixed so I can do the conversions, or you can have your lousy Adobe PDF Pack back and refund my money.
