Thank you both. I will try the drivers later as they may help. The Loader program may be too slow for my PC. After running the program in XP compatibility mode and hitting 'retry' randomly and an absurd amount of times, the file download process started. The program says it will take 22 minutes and I already had to hit retry at 1% complete. Will let you know if this finishes. I may need a new serial adapter or will try the drivers.
