Did the purge. Downloaded the app from the webpage link, installed it and it works fine.
I have installed all apps previously from Object Desktop app. I will uninstall it and download a version from the same website I got the Tiles app from. I will reinstall problem apps from the website.
The new version also allows me to choose an installation location which I could not do in the previous version.
Thanks. I think this takes care of it. Nice product.
