It's most likely due to difference in CBM files between your flash memory/other ews and ur engineering station from where u download may be because of
1.check the system service account user.
2.check that rnrp and prias is able to reach from that station check any events.
You have to reset the controller to come out of that situation.
I also faced similar kind of issue in other controller.
One of reason is that Program which is already there in Controller is different that the current downloading.
Second reason is that if there is difference in Compact Builder version (including Build version) between 800xA CS and ES, similar error will popup during download. So better check version details first andmake it similar to avoid controller cold restart.
If version is same then you have to cold restart controller that's last option.
