TRS8520 suddenly stopped scanning--?

[fredericamg]

My TRS8520 has done a great job scanning for years. As of today, "IJ Network Scanner Selector EX2 cannot be found." When I open the Scanner Selector EX2, it says "Select the scanner you want to use from this computer," but it does not list any--it is blank. 

I reinstalled the software and other functions work fine (no problem printing). And if I go to the Control Panel, right-click the TRS8520 icon, and click "Start Scan," it scans! 

But how can I get the Scan Utility to work again? It was great. Very handy.

PSn When I click the Scan Utility icon in my taskbar, I'm seeing this error message:
