hi brian,
now I know what went wrong yesterday. during the repeated converting/recreating of the july2008-file suddenly august had 30 days (from 2nd to 31st), but I didnīt take notice. today, a few minutes after midnight, the recreated july-file had also 30 days from 2nd to 31st.
then i realized the mistake in aug., fixed the bug, then fixed the bug of july by conv/recr and now my july-file is ok!
thanks for help.
cheers, peter
