Can't upload tune to predator - help!!

[Mad Max]

I got the cables, the adapter and the tune....but every time I try to send the tune from my computer to the predator, instead of the download bar going across the screen, it just says file is transferred, the when you go to the next step, it says transfer failed???? I set the baud at the correct speed.
The "canned" diablo tune is still in the cobra. I saved the factory tune onto a cd. From there I tried to upload the custom tune and have had no luck.
Anyone..................... :shrug:

Could the tune be corrupt?

Export either the Extra or Original backup first...if it still doesn't work after that, don't know what to tell you
