RoboRIO Imaging Fail

[AMendenhall]

We are reimaging a roboRIO which has worked for the entire season.
After testing with and without internet connection, with both USB and ethernet connection to the roboRIO, and with the verified correct image version (v19), we cannot resolve this error:

Unable to download image to target. Unable to complete operation because of unexpected error:nisyscfg.lvlib:Format 5.3.vi:2890001<APPEND>

I guess Windows 7 doesn't support html tags in it's error dialogues
