====== Sentinel Error H0031 ======

If you see the following error when starting the program, the dongle requires a patch because it was most likely programmed with an outdated encryption technology (from 2013). Using the instructions below, we will need the dongle’s **C2V** file in order to prepare the patch.

=== Procedure ===
  - Please download the Remote Update System Tool here: **RUS_KTP.exe** https://download.ktp-software.de/RUS_KTP.exe  
  - Using the **RUS_KTP** tool, read the information from your dongle and send it to me as a **.c2v** file.
  - Based on the **.c2v** file, I will generate a dongle-specific update file and provide it to you.
  - Then open the driver/admin interface in your browser at **http://localhost:1947** and navigate to **Update/Attach**.
  - Before doing so, make sure the corresponding dongle is connected to the system.
  - Upload the provided **.v2c** (Vendor to Customer) file (**Select file…**) and confirm the patching process (**Apply File**).
  - You can verify success in your browser at **http://localhost:1947/_int_/features.html**: the features for **SIGMA**, **SIGMA m.e.**, and **PAM** should be enabled again.
