I am now having this same problem all of a sudden with my TSU 3000. Up till now I have had no problems what so ever. Have been using PENG 3.1.3 and firmware v3.9.8. and both computers used have Windows XP service pack 2. I have done everything recommended. Rebooting the computers after each attempt of flashing firmware and downloading PCF's, reinstalled PENG from 2 separate computers that previously had been used while modifying PCF's. What happens now is that I can reflash firmware without a problem and can download the sample PCF's fine. I tried to download Daniels PCF to the pronto from a fresh download from this site and the dreaded message (The CF version is not correct or the memory is corrupt) comes up again. Is it possible that there is a corrupt file dowload that is ilodged in the memory of the Pronto that hasn't been or can not be erased. Therefore anything but a small PCF file will not download as there is not sufficient memory. What to do now? I wish I knew. As the Counting Crows recently sang "you don't know what you've got till it's gone"!
