Hello Dimitris,  

It sounds like you're facing a challenging situation with Trados Studio. Let's try to address the issues step by step.  

**Step 1:** **License Status**  

Since you mentioned that your license is in "available" status, it might be worth reactivating it. Ensure that your license is properly activated on the same computer you are using. This could potentially resolve some of the issues you're experiencing.  

**Step 2:** **Reset Trados Studio Settings**  

To reset your Trados Studio settings, follow these steps:  

1. Close Trados Studio.  

2. Navigate to the following folder:  

  - For Trados Studio 2024: `C:\Users\[Your_Username]\AppData\Roaming\SDL\SDL Trados Studio\18.0.0.0`  

3. Rename the folder `18.0.0.0` to `18.0.0.0_old`.  

4. Restart Trados Studio.  

This will reset your settings to default and may resolve the "Object reference not set to an instance of an object" error.  

**Step 3:** **Repair Installation**  

If the issue persists, consider performing a repair installation:  

1. Close all RWS applications.  

2. Open Control Panel and navigate to Programs and Features.  

3. Select Trados Studio and choose the Repair option.  

4. Restart Trados Studio after the repair is complete.  

**Step 4:** **Check for Updates**  

Make sure that you have the latest updates installed for both Trados Studio and MultiTerm. You can check for updates by going to Help > Check for Updates within the application.  

**Step 5:** **Clean Reinstall**  

If none of the above steps work, you may need to perform a clean reinstall:  

1. Uninstall Trados Studio and MultiTerm.  

2. Manually delete any remaining folders related to Trados Studio and MultiTerm as mentioned in your query.  

3. Reinstall both applications.  

**Step 6:** **Accessing Termbase Settings**  

For the "Failed to create setting page" error, after resetting your settings, try accessing the termbase settings again. If the issue continues, it may require further investigation.  

I hope these steps help you resolve the issues you're facing. If you have any further questions or if the problem persists, please feel free to ask!
