Spirit_Dongle

I am using STM32L151CBU6 and SPIRIT1 for wireless sensor design. I made my own boar reference SPIRIT1_DONGLE_REVa. When I used SPIRIT1_WMBUS_Example.eww to debug my boar,I find that there are wanting five source files. These files are c:\users\salvo pecorino\Documents\spirit1\Devkits\Firmwave\wmbus_libraries\Link\src\wmbus_crc.c,c:\users\salvo pecorino\Documents\spirit1\Devkits\Firmwave\wmbus_libraries\Link\src\wmbus_linkserices.c,c:\users\salvo pecorino\Documents\spirit1\Devkits\Firmwave\wmbus_libraries\Link\src\wmbus_link.c, c:\users\salvo pecorino\Documents\spirit1\Devkits\Firmwave\wmbus_libraries\Link\src\wmbus_phy.c, c:\program Files(x86)\IAR systems\Embedded workbanch 6.4\arm\inc\c\Dlib_product_string.h . How can I solve the problem? Or how can I get the files? Many thanks.
