After purchasing the paid version, I downloaded it and upon activation I received a fatal error. After several emails to support the issue was resolved and was found to be an error with a single command that WAMP didn't like. Since I hosted this locally, they were unable to login and see where it was happening but with a little information, they were able to solve the problem. It only took about 30 minutes and I was up and running. They were very courteous and understanding. I LOVE this software. I am able to track all my vacation rental property and am not reliant on outside wordpress software or websites.
