CCI: Error Help

[king_boo_boo666]

Hey,
I am having trouble figuring out what the problem is when i try to compile the Goku created in CCI.
I have added transformation effects and sounds, but the same to error messages come up

<< Goku_Blue_Gi >>
.ClassExtension.core(118) : error 017: undefined symbol "CORE"
.ClassExtension.core(131) : error 017: undefined symbol "CORE"
0.28125 Seconds

I know where the error is located in the coreextension file, but i don't know what the exact problem is.

Please help?

Thanks
