Luckily I have a backup and this issue was worked around,
Forgot to mention:
If things goes very bad, you will see files at %ProjectTemp\BLExact_Update_Backup
--> ex: Temp\Win10PESE\BLExact_Update_Backup\2017101921451_Win10PESE\
There you will find folders and .cmd files like
XCopy_Restore_Backup_2017101921451_Win10PESE.cmd
==> This will revert back all changes

new: Utils\Update xxx (Exact and Secure) plugin on server (v44)
It is there since first days of plugins,
but never required yet, only first time with your AU3381.exe.
Since you are a power user better also inform.
