This upgrade is indeed 100% sucessful and I would just like to add the following tips that may help others:
1. On the machine I used for the upgrade simply double clicking on the REG file did not work, this may be due to XP Service Pack 3 that was just installed. If you have this problem use START then RUN and use a command line like this:
regedit c:\HWK 2.0.7 Solution.reg
The above assumes that you put the REG file in the root of C:
2. Remove UFS drivers in DEVICE MANAGER
3. Download these drivers: прикрепил
4. UNRAR the drivers and save in a obvious location
5. Unplug UFS Box
6. Replug UFS Box after 30 seconds
7. When XP asks for drivers ensure that XP loads these new drivers.
8. Run UPDATECLIENT.EXE
9. Admire your UFS Box with V2.8 firmware!!
