No condition visible: no data --> error

Hi,

Yesterday, it worked. Today I added some additional ROIs and removed other ones and now I noticed that the condition field in conn is empty.
It is set from 0 to Inf, but it says "no data selected" under Experiment design.
When running conn, this is the error I get:

ERROR DESCRIPTION:

Error using subsref
Reference to non-existent field 't'.
Error in spm_get_defaults (line 41)
varargout{1} = subsref(defaults, subs);
Error in spm_hrf (line 44)
fMRI_T = spm_get_defaults('stats.fmri.t');
Error in conn_process (line 404)

Error in conn_menumanager (line 119)
feval(CONN_MM.MENU{n0}.callback{n1}{1},CONN_MM.MENU{n0}.callback{n1}{2:end});
CONN v.16.b

Any thoughts?

Thanks
