Bootloader Rejected - Multiple PCMs Different Calibration Files

Any ideas why I'm having difficulty with an update or full flash? This is the error I get...

This happens with two PCMs. Both are programming fine with GM's TIS-SPS system. EFILive will only read the calibration file, not write.

Do you have any other PCM's there that haven't been touched by TIS?

I don't, but the problem resolved with a laptop reboot.
