Tacx Vortex: I've lost speed output following a firmware update.

Thanks for the info Alex, I believe the 3.1.22/0.4.3 firmware is the latest version. Or at least that's what my app is telling me.

Strange, I see this topic at the top of the forum section:

If I download TacxUpdate.exe from google drive and install on a Windows pc do I also download the formware files https://drive.google.com/file/d/15FuCzenzBD93uRCLI6yxNGhqr_5hJ6Md/view as well?
And if so, where do I copy the files to once downloaded?

Yes. From the utility, you will need to specify the path to the firmware file.

Do you mean place the Windows Laptop, with bluetooth switch on, close to the trainer?

This utility does not work with bluetooth. You need an ANT+ antenna.

That's a shame. I don't have an Ant+ Antenna. 

One more moment. You claim from the first post that the problem is caused by a firmware update. But just in case, I would check how tightly the right side (electro unit) fits the resistance unit:
