  Recently, we have applied for the first time the angular momentum and isospin
projected nuclear density functional theory to calculate the isospin-symmetry
breaking (ISB) corrections to the superallowed beta-decay. With the calculated
set of the ISB corrections we found |V_{ud}|=0.97447(23) for the leading
element of the Cabibbo-Kobayashi-Maskawa matrix. This is in nice agreement with
both the recent result of Towner and Hardy [Phys. Rev. {\bf C77}, 025501
(2008)] and the central value deduced from the neutron decay. In this work we
extend our calculations of the ISB corrections covering all superallowed
transitions A,I^\pi=0^+,T=1,T_z \rightarrow A,I^\pi=0^+,T=1,T_z+1 with T_z
=-1,0 and A ranging from 10 to 74.
