Check Sum Error

Has anyone transferred .syx files via USB to a Alesis DM10 module? I downloaded the files it seems with out a problem from The DM10, saved them as a .syx file. Then when I try to upload it back to the module theI get a check sum error and a screen appears on the Alesis DM10 saying waiting for midi connection? How would I fix this?

the typical problems are:
- faulty MIDI drivers -- you should update your MIDI drivers
- sending too fast for device -- you should configure Send SX to send slower (in the settings)
- broken MIDI cable
