The recorder has a line out. There absolutely no reason on God's green earth you would need to use the headphone jack to transfer.
If you don't have it already got to Radio Shack or any electronics store and buy a cable with a 1/8" male stereo plug on each end. Go from the line out of your recorder to the line in on your sound card. Go to the Windows sound mixer choose properties for recording devices. Make sure line in is selected and at 100% volume, otherwise you won't get the complete level of your recording. Use whatever audio software you have, Adobe Audition, Soundforge, etc...
If you don't have any of those Audacity is free and easy to use. Choose to record a new file at 44.1KHz/16 bit which is CD standard. Save it as a single WAV file and use CD Wave to split the tracks. As a matter of fact, you can even use CD Wave to record and save yourself a step.
Last step is burn to CD or encode to whatever format you like.
