Unable to update gui language!

[haky]

The model of my router is RAX50, but doesn't included in the given list!

Problem:

The firmware version of my router is V1.0.3.96, while the GUI language version is 1.0.2.72.

When I checked for update, it showes the latest GUI language version is 1.0.2.82.

And I clicked the update button.

But it failed to finish the update!

Could you provide with the download link of GUI language file?
