Need help with bill reminder desktop gadget.

Hi experts,
My computer is now running with Windows 7 operating system. I have to collect a huge amount of bills from my client's they give me a specific date for asking payment. But it is hard to remind properly. I have tried to download bill reminder desktop gadget but it can't be downloaded. I don't understand what's the problem. In the midway of downloading it shows download is declined.
Can you help me with that?
