Hi,
to sync up where we are currently, are you saying a previous NTLite process was stuck in the background?
If so, best would be to restart the OS, delete the image edit and start fresh from the ISO.
Use the latest version, today had an update as well - nothing related to this though.
If it's stuck again, please post the log of that being stuck - should not happen, but if a previous process was somehow in a limbo, it would explain it.
