Error in 2nd level analysis of group ICA

Dear CONN toolbox users,

I run group ICA analysis with 3 subjects. After 2nd level analysis, it shows summary of it without any problem but, I can not run the spatial component and the temporal component calculation to get data of each ICA components. Is there anyone having any clue what I should do to resolve this error?
