Thanks for inquiring re. Sunfrog Film Scheduling. 
The program is compatible for Windows XP but not for Windows 7 (due 
to changes in the .Net framework).  
You can buy a monthly rental or full version by following this link:
  Sunfrog Film Scheduling
Existing full version customers can write info@sunfrog-tech.com for support.
You can find documentation here.
Best,
