Hi @Mariá Lorenzo Vioque,

I would suggest this error is being caused by your Active X settings in your Internet Explorer

Therefore please ensure your ACTIVE X settings are enabled-

(Close Studio)

1. Open Internet Explorer.
2. Click the Tools menu, and then click Internet Options.
3. On the Security tab, click the Custom level button.
4. Scroll down the Security Settings list until you see ActiveX controls and plug-ins.
5. For Automatic prompting for ActiveX controls, click Enable.

Then restart Studio and see now if you can work with the file.
