Sirsidoo Glad to hear the new driver fixed it.
I guess it's not relevant now, but for future reference (for example if you want to delete an object on a lot you don't own): When you click the ground of any lot, or even outside a proper lot, you should see two options that list NRaas MasterController. Choosing one opens the usual list with options like Reset Lot and Object Stats (this would be the purge option). Selecting the other one should show you two options: Radius Add to Inventory and Radius Purge. You might need the MC Cheats add-on to see these, but it's been so long since I played without MC Cheats that I'm not sure.
The benefits of these options are that you can purge a single item near where you're clicking rather than every instance of that item on a lot, and that you can figure out what something is or what items are nearby. I use this all the time without actually adding to inventory or purging, for example if I want to know whether a metal is silver or palladium, which look too similar for me to tell them apart by their thumbnails.
