I can`t solve this equation

 i want to create matrix that it`s element are matrix.
for example my matrix is 3*3 and elements are 2*2
in addition my element-matrix elements are unknown(x11,x12,........)

 If you see my last question "use fsolve or matrix dissection"CCC.mw 

I want to find C, i finally solve it and get My special C

Now , I Want tolve My problem in block mode,
CCCd.mw

this means that, My matrix elemnts are block matrix, and search for result,

 hi
