Initially, it was fairly complicated. Topaz leverages the functionality from other products quite a bit, and the setup issues were attributed to those other products: things that we didn't have in place, we didn't have installed, we didn't have configured. I spent a lot of time going through the features of Topaz that were not working, trying to find which product it was that was missing a configuration step or a setup step. That took me the better part of six to eight months to get it all ironed out. It was fairly complicated to get all of the features and functions working. As far as Topaz itself goes, they're just built-in and expected to work, but as I said, those features are really attributed to other products, the setup and configuration that's required for those products. But since we've gone through those initial setups, doing upgrades and doing maintenance has been really straightforward. There has really not been a lot to do in the configuration and setup portions.
