Does anyone know how to resolve this? I can't find an "edit assets" screen. The tab at the top saying edit assets/content doesn't seem to have anything that can build an index file that I can see. Thanks.
Couple of things to try TS-Tools was installed as administrator? Open Route Building Tools menu and select Extract RouteProperties.xml (if needed for .ap file)and then Index Route Properties and all should work OK. Index Route Properties has to be run after the addition of any DLC regardless of its origin. Hope this works!!
