Graxpert failing to open after update

DavesView:
Upon opening PI this morning, I received an update notification for Utilities. I let it update and now Graxpert doesn't work. The following error pops up:
run --execute-mode=auto "C:/Program Files/PixInsight/src/scripts/Toolbox/Graxpert.js" Processing script file: C:/Program Files/PixInsight/src/scripts/Toolbox/Graxpert.js*** Error: Signature verification failed for 'GraXpert': Invalid code signature: C:/Program Files/PixInsight/src/scripts/Toolbox/Graxpert.js

*Hi David,

I had the same problem. Temporary you can go to:
C:/Program Files/PixInsight/src/scripts/Toolbox/

and rename Graxpert.xsgn file to something else (i am not behind computer but I think this is the filename, its only another Graxpert.* file besides .js). This will disable verification and allow you to use GraXpert.

Hello.
I had the same problem but I have found the solution with the help of my friend Régis also in Astrobin. 
in fact, there’s a new version of the software on the Pixinsight website since January 19.
You just have to delete your old version and to download and reinstall the new one.
After, there is no problem and you can use easily expert and all the scripts of the toolbox.
I hope that will help you.

Sorry for my poor English.

Reinstalling the latest version of PixInsight fixes the problem, too.

I tried  to change the name, but it disappeared from the toolbox in Pixin. Can you please give an example of your rename?
