This is an excellent disk catalog tool. Unfortunately my experience with the developer is the same as others. I haven't used the application for years and wanted to get back into it. My license file and serial number went missing over the years of upgrading email clients and external hard drives.
I sent one request for a new license file; the developer never responded. I sent another request, attached an email from him dated 2003 as some amount of proof. His response:
This request violates conditions for proper license use and license reissuing in more ways than I can count. Not only there is no proper identification as a registered user of any kind, the one very vague detail that is provided is incorrect, and you are actually attempting to receive the license to a freemail address. This kind of actions directly promote fraud and are not tolerated.
Given there were repeated attempts in violation of stated conditions, the privilege of reissuing lost licenses is now void for this license.
The irony is I sent this from my MobileMe email address which costs me $99 per year. I'm unclear how that is Freemail.
You've been warned.
