Import TerraSAR-X data after update

I cannot import my TerraSAR-X data when I click File/Import/Sar Sensors/Terrasar x . Attached picture is error message. Pls help about this.

That’s strange. But I think this indicates that your SNAP installation is not healthy. First try to update all installed modules, by selecting from the menu Help / Check for Updates and follow the instructions. If this does not help, please try to reinstall SNAP and apply all updates.
