Did you buy the flashpro new or used? Were you able to verify that it was unlocked if it was used? What tune did you try to upload and from where did you get it? The file could be corrupted. The battery could be low. Could be a number of different things. I would take the stock factory tune, that should have been saved to your PC, reupload it to the hondata, then reflash the ECU and see where you're at.
