As you have installed CF 8 server on Unix operating system, where only CF 8 enterprise license key is supported whereas it looks that you are putting CF 8 standard license key there so finally its not updated as correct licensed CF server.
Kindly go though the Solaris section of CF 8 support matrix http://www.adobe.com/products/coldfusion/pdfs/cf8_systemsupportmatrix. pdf for compatible environment/tools/Sws etc.
