In the meantime, based on the information you have provided, here is a suggested answer to your question:

Hello Herman,

It seems like you've already taken some good steps to troubleshoot this issue. However, there are a few more things you can try:

Step 1: Confirm your DeepL subscription. The DeepL API V2 requires a DeepL Pro Advanced or Ultimate subscription. If you don't have one of these, you won't be able to use the V2 API.

Step 2: Check your API key. Make sure you're using the correct API key for the V2 API. The keys for V1 and V2 are different, so you'll need to generate a new key for V2.

Step 3: Update your plugin. Ensure you have the latest version of the DeepL plugin installed. You can check for updates within the application or visit the RWS AppStore.

Step 4: Reinstall the plugin. If you're still having issues, try uninstalling and reinstalling the plugin again. Sometimes, this can resolve any issues that might have occurred during the initial installation.

Step 5: Check for Trados Studio updates. Make sure your Trados Studio is up-to-date. You can check for updates within the application.

If you've tried all these steps and are still having issues, it's possible that there might be a compatibility issue between the DeepL V2 API and Trados Studio. While some users have reported being able to use the V2 API with Trados Studio, it's not officially supported and your experience may vary.
