Can't load su2021 pro

Good Morning
cant get su to load, when i click on icon the su2021 pro screen appears and then nothing same with trying to anything else su.
My su file is also gone from the download folder… any advice.

There was a change in the sign in process pushed a little bit ago. See:

I wonder if that has anything to do with it. Can you go to and sign in?

What “su file” are you referring to? The installer? If that’s what you are looking for go to to get it. Couldn’t hurt to download the installer and then right click on it, choose Run as administrator and then, if prompted, choose Repair.

thanks again for your assistance, new sign all that was required
