Hey there basj, thanks for your answer! But sadly it didn't work...

mind that my version of Start10 is the steam one (purchased it through the stardock Humble Bundle).

I've purged the app, and have tried to initiate the software from steam, but now I even cannot open the app (before the purge I could to it, though changing settings didn't do anything).

Thanks in advance for your answer!

Edit: I'm re-installing it through steam. It doesn't let me download latest version, so I'm downloading an old one and updating from the app.

Edit2: it's working now!

This was the process, in case anyone finds the same problem:

- I went to steam app. Right-click on Start10 -> Properties.

- Go to Local Files, then click on "See local files".

- A folder will open. You will have your installer there. Double-click.

- It will tell you that is an old installer, and if you would like to download the newest one. Click on "No" (the newest doesn't work).

- You will install an old version. As soon it's installed, it will tell you that there exists a new version, and if you would like to install it. Click on "Yes". Now it will work. It's a silly workaround, but well... it does work.

Thanks for your help Basj!

Just making a new reply to let you know it's working now, as when I edited last answer you had already replied.
