All requested features have already been authorized on this machine
My single-use personal ArcGIS pro license expired last week, but I have a new authorization file for this year. I have previously renewed my license without issue, but now it is telling me that “[a]ll requested features have already been authorized on this machine” despite the file showing as “expired” on the availability window. Has anyone encountered this problem before and does anyone know how to fix it?

Trying to create a store locator that will accept KML data and use the polygons as the "store"
I have a client that needs a store locator that behaves differently than just address pins on the map.
Each location's address is irrelevant in this instance, only the service area, or territory. I have KML data but am having difficulty finding software that, A) lets me import the KML files to create clickable polygons that display the location's website link and phone, and, B) includes a search feature like most store locators. Any insights?

How to digitize
How to digitize
In a lay man's language, digitizing is the process of converting information to digital format, in this case maps. Digitizing converts raster data to vector data which can then be used for analysis this give various results. I am going to outline the process of georefrencing and digitizing using three common softwares which are ArcGis, QGIS, Grass and AutoCAD.
