X2Pro with Mac OS Big Sur

If you have downloaded the latest version from the App store then it should work with Big Sur, if it is refusing to run due to a security message you could try removing and re installing in from the App store or this may help:

Run X2Pro. You will get a message telling you that it cannot be run because it can't be checked for malicious software. Dismiss that dialog.
Go to System Preferences. Select Security & Privacy and go to the General tab.
At the bottom there will be a message telling you that X2Pro was blocked from running. Click the button next to the message. 
Run X2Pro again. The dialog telling you that it cannot be run will have an Open button on it. Click this and X2Pro will run.
Once you have done this you should no longer get any messages when trying to run X2Pro.

Hello,

I updated my macOS to Big Sur and X2Pro is not working anymore.
Is there an update available?

Thank you in advance for your help.
