UBB.Developers Forums UBB.threads 7 Development How Do I? Problem updating thread files

When i upgraded from UBB5.47c to UBB6 i got an error with the thread files

i opened one for a clean UBB6 and one for my apparently upgraded UBB6

and it wasn't in the
%forum_topics = (
"000001" => q|2451974.2329|,
"000002" => q|2451971.1542|,
);
1;

format

what i got was the old UBB5 style

2451983.1924|^|000702|^|Battle figures|^|0|^|tabyther|^|200103141924|^|no|^|1|^|tabyther

is there anything i could have done wrong...
